Possible to run behind Traefik reverse proxy?

[Roger-Roger-debug]

I'm using Traefik on my server and would like to use it as a reverse proxy for broadcast-box. However, to route network between containers, Traefik needs to share a network, meaning I can't set the network mode to host like in the example config for caddy.

This is what I currently have. It listens for https connections for my.stream.url and routes any connections to the internal 8080 port. It opens up 8080/udp for external connections as well.

With this the webui works, but trying to stream fails. I had hoped that just giving access to 8080/udp would make it work, but that doesn't seem to be the case. Is this even possible without host mode?
