Description

Hi, Im using chisel reverse UDP tunnel for wireguard which the wireguard server is a docker container

this is the container info:
47dd02e0a49b ghcr.io/wg-easy/wg-easy "docker-entrypoint.s…" About an hour ago Up About an hour (healthy) 0.0.0.0:22355->22355/udp, :::22355->22355/udp, 0.0.0.0:51821->51821/tcp, :::51821->51821/tcp wg-easy

22355 port is for wg server, 51821 port is for wg ui

when i establish chisel tunnel over udpwith port 2096 (in both servers) and set config tunnel to 22355, the wg docker container cannot get the reverse tunnel traffic

but same works with chisel reverse udp tunnel and wg installed without docker container

also same works with normal nginx udp tunnel and wg docker container

Research direction

Start by reproducing the reverse UDP tunnel with chisel port 2096 forwarding to the wg-easy Docker container's UDP port 22355. Compare it with the working non-Docker WireGuard setup and nginx UDP tunnel, and inspect whether traffic reaches the container; done means the Docker-hosted WireGuard server receives reverse-tunnel traffic.
