Not working, how to debug? #32

Closed cornzzy closed 2 months ago

cornzzy commented 2 months ago

I have the following setup:

wireguard client -> server1 -> server2

wireguard client is simply using wireguard pointing to server1:3535

server1 is running dtlspipe -psk xx client 127.0.0.1:3535 server2:443

server2 is running wireguard listening on 2525 and running dtlspipe -psk xx server 0.0.0.0:443 127.0.0.1:2525

No traffic happens when wg client connects and mtu is 1280. The same routing works with udp2raw. How do I find the issue?

Hello!

If wireguard client and server1 is not the same machine, then bind address of dtlspipe client is incorrect: you should use wildcard bind address 0.0.0.0 instead of 127.0.0.1.
