Virtual private networks / Weird routing when my openvpn client is up on my firewall
« on: December 03, 2022, 02:55:42 pm »
Hello everyone, I have an issue with my installation and I can't figure out what's going on.
I have installed an openvpn client on the firewall that only routes the traffic from a specific IP in my network and that works great (with a kill switch if it goes down).
Now I have installed wireguard server by following the doc (very well explained), except that's where something weird happens: if openvpn is down, it works perfectly fine, but if openvpn is up, the out traffic of wireguard is somehow routed through openvpn and it doesn't work at all (I had a similar issue while trying to set up a vlan guest, a soon as I turend openvpn it would't work).
We can see it come in through WAN (from my mobile phone), but what leaves is through ProtonCH which is my openvpn client.
I'm completely lost and would love some input
Thank you!
I can share any config if needed.
