Recently after setting up a Site to Site VPN between two Unifi Dream Machine Pro’s, I noticed the remote site was not resolving the active directory domain, the computers could also no longer update group policies or connect to the server. Everything else was working correctly and It took a few moments to figure out the simple issue. It turned out to be the Content Filtering profile.
- On the remote Unifi Dream Machine, select your network.
- Under the “Content FIltering” make sure None is selected. This setting will overide your set DNS settings.
I have the same issue since I got to Zone Based Firewall. I have Firewall rules in Place, but that does not matter. And this is also a Topic of to less loging in Unify. It would so nice to see something like that in a logfile… And btw. I guess man Companys have different VLANs and would like to use Content filtering and Active Directory at the same time…
