Guest LAN can't access internet after VPN change
-
I recently moved from PIAVPN to Mullvad. Everything went easily with the change except one thing: my guest network can no longer access the internet after the change. I spent about 4 hours this morning looking at logs and trying to determine the source of the problem and the furthest I could get is some strange entries in the states table that seems to show that the traffic is going out one interface and back via another:
This doesn't seem right to me, although I may be barking up the wrong tree. If the above is indeed the sign of the issue, what might the issue be?
Clients on the guest network can:
- lookup IPs via DNS
- ping internet resources (8.8.8.8 for example)
Clients on the guest network cannot:
- ping the gateway interface (192.168.20.1)
- connect to anything in a browser
Details of my setup:
- Guest network is all over wifi via a few Unifi APs with clan tagging.
- Have a main network with partioned IPs: below .50 bypasss VPN, above .50 routes over VPN
- All guest network connections are supposed to bypass VPN
