Windows Firewall – How to bypass AD-policy and allow inbound traffic

Posted on October 16, 2014 by Peter

In some cases i.e support and other troubleshooting issues you have to temporary disable or allow all traffic through Windows Firewall.

1. Open regedit.exe and browse to
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsFirewall\DomainProfile
(This key does not exist if there is no AD-policy affecting your machine)

2. Change the DWORD “DefaultInboundAction” to “0”.

3. Restart the Windows Firewall service.

4. This setting will remain until next policy update.
