I’ve got a few networks set up, VPN is connected and on my device that is connected with the VPN, I can still access the Unifi interface by connecting to the IP via browser. Unifi devices are on their own subet, 192.168.1.x, VPN is 192.168.5.x, and my other network is 192.168.2.x.
I can’t ping anything on the 192.168.2.x nor can I connect to any of their web interfaces (eg a PiKVN). I cannot SSH to any of the Linux machines, however I’m for some reason able to RDP to the Windows machines even though I cannot ping them.
Really confused what’s going on. Previously I had everything working but not sure if after some updates some parts stopped working so I reset the VPN and now it’s all weird like this.
I’ve tried the previously suggested idea of using a different IP range, eg: 172.x.x.x, but that resulted in the same behavior.

For me it was for some reason related to a traffic rule. I had a traffic rule that blocked internet for one device on my network – completely unrelated and untied to the VPN.
I disabled the traffic rule and suddenly I’m able to reach everything on the network. I tested this a few times (turning it on and off), and this was indeed the cause for me. Seems like a weird bug. I instead of using the traffic rule, made a firewall rule for that device (actually removed all traffic rules as they seem to be a bit less precise).
