Firewall policy settings for tenant attached devices in Microsoft Intune

  • Άρθρο

View the Microsoft Windows Firewall settings you can manage with the Windows Firewall (ConfigMgr) profile from Intune. The profile is available when you configure Intune Firewall policy, and the policy deploys to devices you manage with Configuration Manager when you've configured the tenant attach scenario.

Windows Firewall

  • Certificate revocation list verification (Device)
    CSP: MdmStore/Global/CRLcheck

    Specify how certificate revocation list (CRL) verification is enforced.

    • Not configured (default) - Use the client default, which is to disable CRL verification.
    • None
    • Attempt
    • Require

  • Disable Stateful Ftp (Device)
    CSP: MdmStore/Global/DisableStatefulFtp

    • Not configured (default)
    • True - Stateful FTP is disabled
    • False - The firewall performs stateful File Transfer Protocol (FTP) filtering to allow secondary connections.

  • Enable Packet Queue (Device)
    CSP: MdmStore/Global/EnablePacketQueue

    Select from the following options to configure scaling for the software on the receive side for the encrypted receive and clear text forward for the IPsec tunnel gateway scenario. This ensures the packet order is preserved. By default, no options are selected.

    • Disabled
    • Queue Inbound
    • Queue Outbound

  • IPsec Exceptions (Device)
    CSP: MdmStore/Global/IPsecExempt

    Select from the following options to configure IPsec exceptions.

    • Exempt ICMP from IPsec
    • Exempt router discover IPv6 ICMP type-codes from IPsec

  • Security association idle time (Device)
    CSP: MdmStore/Global/SaIdleTime

    Specify a time in seconds between 300 and 3600, for how long the security associations are kept after network traffic isn't seen. If you don't specify any value, the system deletes a security association after it's been idle for 300 seconds.
