OpenVPN Connections to Domain
-
I have recently updated our PFSense boxes to the latest version of PFSense 21.02-Release-p1 and I am now having issues with devices communicating back to our primary location. For reference, we are using a hub and spoke model consisting of 5 PFSense devices. One device is acting as our primary OpenVPN server with the other 4 location being clients connecting back to the server. All of these clients have been set up to allow for communication between all 5 sites. After the updates we did over the weekend, some of the client sites have lost the ability to communicate back to our primary and secondary domain controllers and DNS servers. When I attempt to ping devices by their IP from a windows machine, I am getting replies. When i ping FQDN names, some return and some do not. I am also having issues getting SMTP traffic to move in our domain and i have created rules to allow for this traffic to pass through the firewall. Also, our PFSense boxes are all connected to other routers providing the ISP connection. Some have been turned into bridge mode and some have not. Either way though, I am seeing issues with bridged and non-bridged connections. What am I missing?
