Running this container with proxy

[Dxtros]

I spent a while trying to get my valheim server in docker to run through my pangolin proxy on my vps.

I was baffled at how it seemed to get through my router networking and still make itself online despite not forwarding router ports or docker ports.

Is there a way to force game traffic through a proxy so my home public IP isn't used for connections? It seems no matter the configuration it would not use my proxy. The only way i made it not go out my home ip was making ip table rules but then the networking wouldn't work even though it was able to talk to my proxy tunnel.

I have crossplay enabled and i think the playfab backend circumvents my proxy. does playfab use hole punching to transfer game traffic? Can i force it to use my proxy instead of my home router?

any suggestions are much appreciated
