|Hello, I am trying to set up an openWRT VPN container in Proxmox. I have managed to set it up such that when I enable the vpn, all the containers that are connected to the lan bridge of the OpenWRT container get assigned IP addresses by openWRT and get public facing IPs behing the PIA VPN. The issue I am running into right now is as soon as I enable the VPN, I can no longer ping the openWRT container from my home network and I cannot connect to the web server. That being said, typing ip a inside the OpenWRT container shows me that I do in fact have an IP assigned by my actual router (same IP I used to connect to the web interface before I couldnt anymore). As soon as I disable the VPN by editing /etc/config/openvpn I am able to connect to the container again. Can anyone help me with this? For reference I used 172.20.20.1/24 as the lan IP of the OpenWRT router (its wan IP is 10.0.2.95).|
If you search the forum, you will see that running a containerized instance of OpenWrt isn't really supported -- yes, it will run, but there are key networking features that will not function as expected due to the nuance of how containers work.
That being said, the OpenWrt container is likely either rejecting inbound traffic as a function of the VPN, or it is (mis-)directing the responses through the tunnel. This because of how the container's networking is configured -- if you run bare metal (or even possibly with a regular VM), you would not experience this issue.
