Microsoft Windows DirectAccess connection disconnects when Elements Endpoint Protection firewall profile is enabled

Issue:

Microsoft Windows DirectAccess connection disconnects / cuts off / drops intermittently when Elements Endpoint Protection firewall profile is enabled.
 

Resolution:

If you are using WithSecure firewall profile, it will by default block unknown outbound connections, so you will need to make sure that you have all the required firewall rules in place if you want to have the DirectAccess connection working. 

Please follow this Microsoft guide regarding Direct Access firewall rules: Step 1 Plan the Advanced DirectAccess Infrastructure | Microsoft Learn

Note that if you use GPO to configure the Windows Firewall, in most cases it is best to turn off the WithSecure firewall profiles to avoid conflicts, since GPO firewall rules will always override any WithSecure created firewall rules. To turn off the WithSecure firewall profile:

1. Log in to the Elements Security Center portal
2. Navigate to the Security Configurations > Profiles page
3. Open the profile that is in use on the devices
4. Go to the Firewall settings page
5. In the Global setting section, from the WithSecure firewall mode drop-down menu, select Do nothing
6. Click Save profile
