DESCRIPTION
The New-NetIPsecMainModeRule cmdlet creates an IPsec main mode rule.
A main mode rule contains a set of local and remote end points to determine the peers to which it applies. When an application on the local
computer attempts to communicate with one of these specified remote hosts, the computer attempts to establish a security association (SA) with the
remote server.
In order to set up this SA, the computers need to agree on how to authenticate with each other. The local computer will only agree to use one of
the proposals from the network IPsec phase 1 authorization set associated with the main mode rule. See the New-NetIPsecPhase1AuthSet cmdlet for
more information. When the negotiation is successful a main mode SA is created. See the Get-NetIPsecMainModeSA cmdlet for more information.
The computers also need to agree on common encryption, hashing, and key exchange methods. The local computer will only agree to use one of the
cryptographic methods contained in the IPsec main mode cryptographic set associated with the main mode rule. See the New-NetIPsecMainModeCryptoSet
cmdlet for more information. When the negotiation is successful a quick mode SA is created. See the Get-NetIPsecQuickModeSA cmdlet for more
information.
A main mode rule offers four mandatory parameters that negotiated as part of the main mode security association (SA):
-- The computer authentication method: Kerberos v5, certificate, or pre-shared key authentication that is provided by the NetIPsecPhase1AuthSet
object.
-- The encryption algorithm that is provided by the NetIPsecMainModeCryptoSet object.
-- The hashing algorithm that is provided by the NetIPsecMainModeCryptoSet object.
-- The Diffie-Hellman (DH) key exchange group to be used for the base keying material that is provided by the NetIPsecMainModeCryptoSet object.
Note: Each main mode rule must be created in the policy store of the associated IPsec rule. If a particular rule applies to multiple IPsec rules
in different policy stores (GPOs), then the rule must be duplicated for each of those stores (so that policies can be updated without linking
issues). See the Copy-NetFirewallRule, Copy-NetIPsecMainModeCryptoSet, Copy-NetIPsecMainModeRule, Copy-NetIPsecPhase1AuthSet,
Copy-NetIPsecPhase2AuthSet, Copy-NetIPsecQuickModeCryptoSet, or Copy-NetIPsecRule cmdlet for more information.
PARAMETERS
-AsJob [<SwitchParameter>]
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the
session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet.
For more information about Windows PowerShell???? background jobs, see about_Jobs.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-CimSession <CimSession[]>
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession
or Get-CimSession cmdlet. The default is the current session on the local computer.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-Description <String>
Specifies that matching firewall rules of the indicated description are created. Wildcard characters are accepted.
This parameter provides information about the firewall rule. This parameter specifies the localized, user-facing description of the IPsec rule.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-DisplayName <String>
Specifies that only matching firewall rules of the indicated display name are created. Wildcard characters are accepted.
Specifies the localized, user-facing name of the firewall rule being created. When creating a rule this parameter is required. This parameter
value is locale-dependent. If the object is not modified, this parameter value may change in certain circumstances. When writing scripts in
multi-lingual environments, the Name parameter should be used instead, where the default value is a randomly assigned value.
Note: This parameter cannot be set to All.
Required? true
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-Enabled <Enabled>
Specifies that matching main mode rules of the indicated state are created.
This parameter specifies that the rule object is administratively enabled or administratively disabled. The acceptable values for this
parameter are:
-- True: Specifies the rule is currently enabled.
-- False: Specifies the rule is currently disabled. A disabled rule will not actively modify computer behavior, but the rule still exists on
the computer so it can be re-enabled.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-GPOSession <String>
Specifies the network GPO from which to retrieve the rules to be created.
This parameter is used in the same way as the PolicyStore parameter. When modifying GPOs in Windows PowerShell????, each change to a GPO requires
the entire GPO to be loaded, modified, and saved back. On a busy Domain Controller (DC), this can be a slow and resource-heavy operation. A
GPO Session loads a domain GPO onto the local computer and makes all changes in a batch, before saving it back. This reduces the load on the
DC and speeds up the Windows PowerShell cmdlets. To load a GPO Session, use the Open-NetGPO cmdlet. To save a GPO Session, use the Save-NetGPO
cmdlet.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-Group <String>
Specifies that only matching firewall rules of the indicated group association are created. Wildcard characters are accepted.
This parameter specifies the source string for the DisplayGroup parameter. If the DisplayGroup parameter value is a localizable string, then
this parameter contains an indirect string. Rule groups can be used to organize rules by influence and allows batch rule modifications. Using
the Set-NetFirewallRule cmdlets, if the group name is specified for a set of rules or sets, then all of the rules or sets in that group
receive the same set of modifications. It is good practice to specify this parameter value with a universal and world-ready indirect
@FirewallAPI name.
Note: The DisplayGroup parameter cannot be specified upon object creation using the New-NetFirewallRule cmdlet, but can be modified using
dot-notation and the Set-NetFirewallRule cmdlet.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-LocalAddress <String[]>
Specifies that network packets with matching IP addresses match this rule.
This parameter value is the first end point of an IPsec rule and specifies the computers that are subject to the requirements of this rule.
This parameter value is an IPv4 or IPv6 address, hostname, subnet, range, or the following keyword: Any.
The acceptable formats for this parameter are:
-- Single IPv4 Address: 1.2.3.4
-- Single IPv6 Address: fe80::1
-- IPv4 Subnet (by network bit count): 1.2.3.4/24
-- IPv6 Subnet (by network bit count): fe80::1/48
-- IPv4 Subnet (by network mask): 1.2.3.4/255.255.255.0
-- IPv4 Range: 1.2.3.4 through 1.2.3.7
-- IPv6 Range: fe80::1 through fe80::9
Note: Querying for rules with this parameter can only be performed using filter objects. See the Get-NetFirewallAddressFilter cmdlet for more
information.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-MainModeCryptoSet <String>
Gets the IPsec main mode rules that are associated with the given main mode cryptographic set to be created.
This parameter specifies, by name, the main mode cryptographic set to be associated with the main mode rule.
A NetIPsecMainModeCryptoSet object represents a main mode cryptographic conditions associated with a main mode rule. This parameter sets the
methods for main mode negotiation by describing the proposals for encryption. This is only associated with main mode rules. See the
Get-NetIPsecMainModeCryptoSet cmdlet for more information. Alternatively, the AssociatedNetIPsecMainModeCryptoSet parameter can be used for
the same purpose, but is used to pipe the input set into the rule.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-Name <String>
Specifies that only matching main mode cryptographic sets of the indicated name are created. Wildcard characters are accepted.
This parameter acts just like a filename, in that only one rule with a given name may exist in a policy store at a time. During group policy
processing and policy merge, rules that have the same name but come from multiple stores being merged, will overwrite one another so that only
one exists. This overwriting behavior is desirable if the rules serve the same purpose. For instance, all of the firewall rules have specific
names, so if an administrator can copy these rules to a GPO, and the rules will override the local versions on a local computer. GPOs can have
precedence. So, if an administrator has a different or more specific rule the same name in a higher-precedence GPO, then it overrides other
rules that exist.
The default value is a randomly assigned value.
When you want to override the defaults for main mode encryption, specify the customized parameters and set this parameter value, making this
parameter the new default setting for encryption.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-Phase1AuthSet <String>
Gets the main mode rules that are associated with the given phase 1 authentication set to be created.
This parameter specifies, by Name, the Phase 1 authentication set to be associated with the main mode rule.
A NetIPsecPhase1AuthSet object represents the phase 1 authentication conditions associated with an IPsec or main mode rule. This parameter
sets the methods for main mode negotiation by describing the proposals for computer authentication. See the New-NetIPsecAuthProposal cmdlet of
more information. Alternatively, the AssociatedNetIPsecPhase1AuthSet parameter can be used for the same purpose, but is used to pipe the input
set into the rule.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-Platform <String[]>
Specifies which version of Windows the associated rule applies.
The acceptable format for this parameter is a number in the Major.Minor format.
The version number of 6.0 corresponds to Vista (WindowsVista), 6.1 corresponds to Win7 (Windows7 or WindowsServer????2008), and 6.2 corresponds
to Win8 (Windows???? 8 or Windows Server 2012).
If + is not specified, then only that version is associated.
If + is specified, then that version and later are associated.
Note: Querying for rules with this parameter with the Get-NetIPsecMainModeRule cmdlet cannot be performed.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-PolicyStore <String>
Specifies the policy store from which to retrieve the sets to be created.
A policy store is a container for firewall and IPsec policy.
The acceptable values for this parameter are:??
-- PersistentStore: Sometimes called static rules, this store contains the persistent policy for the local computer. This policy is not from
GPOs, and has been created manually or programmatically, during application installation, on the computer. Rules created in this store are
attached to the ActiveStore and activated on the computer immediately.
-- ActiveStore: This store contains the currently active policy, which is the sum of all policy stores that apply to the computer. This is
the resultant set of policy (RSOP) for the local computer (the sum of all GPOs that apply to the computer), and the local stores (the
PersistentStore, the Static Windows Service Hardening (WSH), and the Configurable WSH).
---- GPOs are also policy stores. Computer GPOs can be specified as follows.
------ ????????PolicyStore hostname.
---- Active Directory GPOs can be specified as follows.
------ ????????PolicyStore domain.fqdn.com\\GPO_Friendly_Name.
------ Such as the following.
-------- -PolicyStore localhost
-------- -PolicyStore corp.contoso.com\\FirewallPolicy
--- Active Directory GPOs can be created using the New-GPO cmdlet or the Group Policy Management Console.
-- RSOP: This read-only store contains the sum of all GPOs applied to the local computer.
-- SystemDefaults: This read-only store contains the default state of firewall rules that ship with Windows Server???? 2012.
-- StaticServiceStore: This read-only store contains all the service restrictions that ship with Windows Server 2012. Optional and
product-dependent features are considered part of Windows Server 2012 for the purposes of WFAS.
-- ConfigurableServiceStore: This read-write store contains all the service restrictions that are added for third-party services. In
addition, network isolation rules that are created for Windows Store application containers will appear in this policy store.
The default value is PersistentStore.
Note: The Set-NetIPsecMainModeCryptoSet cmdlet cannot be used to add an object to a policy store. An object can only be added to a policy
store at creation time with the Copy-NetIPsecMainModeCryptoSet cmdlet or with this cmdlet.
Required? false
Position? named

Accept pipeline input? false
Accept wildcard characters? false
-Profile <Profile>
Specifies one or more profiles to which the rule is assigned. The rule is active on the local computer only when the specified profile is
currently active. This relationship is many-to-many and can be indirectly modified by the user, by changing the Profiles field on instances of
firewall rules. Only one profile is applied at a time.
The acceptable values for this parameter are:?? Any, Domain, Private, Public, or NotApplicable.
The default value is Any.
Separate multiple entries with a comma and do not include any spaces.
Note: Use the keyword Any to configure the profile as Private, Public, Domain in the ConfigurableServiceStore.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-RemoteAddress <String[]>
Specifies that network packets with matching IP addresses match this rule.
This parameter value is the second end point of an IPsec rule and specifies the computers that are subject to the requirements of this rule.
This parameter value is an IPv4 or IPv6 address, hostname, subnet, range, or the following keyword: Any.
The acceptable formats for this parameter are:

In order to set up this SA, the computers need to agree on how to authenticate with each other. The local computer will only agree to use one of
the proposals from the network IPsec phase 1 authorization set associated with the main mode rule. See the New-NetIPsecPhase1AuthSet cmdlet for

The acceptable values for this parameter are:??
-- PersistentStore: Sometimes called static rules, this store contains the persistent policy for the local computer. This policy is not from
GPOs, and has been created manually or programmatically, during application installation, on the computer. Rules created in this store are
attached to the ActiveStore and activated on the computer immediately.
-- ActiveStore: This store contains the currently active policy, which is the sum of all policy stores that apply to the computer. This is
the resultant set of policy (RSOP) for the local computer (the sum of all GPOs that apply to the computer), and the local stores (the
PersistentStore, the Static Windows Service Hardening (WSH), and the Configurable WSH).
---- GPOs are also policy stores. Computer GPOs can be specified as follows.
------ ????????PolicyStore hostname.
---- Active Directory GPOs can be specified as follows.
------ ????????PolicyStore domain.fqdn.com\\GPO_Friendly_Name.
------ Such as the following.
-------- -PolicyStore localhost
-------- -PolicyStore corp.contoso.com\\FirewallPolicy
--- Active Directory GPOs can be created using the New-GPO cmdlet or the Group Policy Management Console.
-- RSOP: This read-only store contains the sum of all GPOs applied to the local computer.
-- SystemDefaults: This read-only store contains the default state of firewall rules that ship with Windows Server???? 2012.
-- StaticServiceStore: This read-only store contains all the service restrictions that ship with Windows Server 2012. Optional and
product-dependent features are considered part of Windows Server 2012 for the purposes of WFAS.
-- ConfigurableServiceStore: This read-write store contains all the service restrictions that are added for third-party services. In
addition, network isolation rules that are created for Windows Store application containers will appear in this policy store.
The default value is PersistentStore.
Note: The Set-NetIPsecMainModeCryptoSet cmdlet cannot be used to add an object to a policy store. An object can only be added to a policy
store at creation time with the Copy-NetIPsecMainModeCryptoSet cmdlet or with this cmdlet.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-Profile <Profile>
Specifies one or more profiles to which the rule is assigned. The rule is active on the local computer only when the specified profile is
currently active. This relationship is many-to-many and can be indirectly modified by the user, by changing the Profiles field on instances of
firewall rules. Only one profile is applied at a time.
The acceptable values for this parameter are:?? Any, Domain, Private, Public, or NotApplicable.
The default value is Any.
Separate multiple entries with a comma and do not include any spaces.
Note: Use the keyword Any to configure the profile as Private, Public, Domain in the ConfigurableServiceStore.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-RemoteAddress <String[]>
Specifies that network packets with matching IP addresses match this rule.
This parameter value is the second end point of an IPsec rule and specifies the computers that are subject to the requirements of this rule.
This parameter value is an IPv4 or IPv6 address, hostname, subnet, range, or the following keyword: Any.
The acceptable formats for this parameter are:
-- Single IPv4 Address: 1.2.3.4
-- Single IPv6 Address: fe80::1
-- IPv4 Subnet (by network bit count): 1.2.3.4/24
-- IPv6 Subnet (by network bit count): fe80::1/48
-- IPv4 Subnet (by network mask): 1.2.3.4/255.255.255.0
-- IPv4 Range: 1.2.3.4 through 1.2.3.7
-- IPv6 Range: fe80::1 through fe80::9
Note: Querying for rules with this parameter can only be performed using filter objects. See the Get-NetFirewallAddressFilter cmdlet for more
information.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-ThrottleLimit <Int32>
Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0
is entered, then Windows PowerShell???? calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running
on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-Confirm [<SwitchParameter>]
Prompts you for confirmation before running the cmdlet.
Required? false
Position? named
Default value false
Accept pipeline input? false
Accept wildcard characters? false
-WhatIf [<SwitchParameter>]
Shows what would happen if the cmdlet runs. The cmdlet is not run.
Required? false
Position? named
Default value false
Accept pipeline input? false
Accept wildcard characters? false
<CommonParameters>
This cmdlet supports the common parameters: Verbose, Debug,
ErrorAction, ErrorVariable, WarningAction, WarningVariable,
OutBuffer, PipelineVariable, and OutVariable. For more information, see
