ip: invalid argument '51820' to 'table' #11

Open Neurrone opened 4 years ago

I'm getting the following error:

INFO: (wg0) 2020/06/02 15:11:48 Starting wireguard-go version 0.0.20200320
[#] wg setconf wg0 /dev/fd/63

ip: invalid argument '51820' to 'table'
[#] resolvconf -d wg0 -f

The configure file is as follows:

[Interface]
PrivateKey = ...
Address = 10.67.113.92/32
DNS = 8.8.8.8

[Peer]
PublicKey = ...
AllowedIPs = 0.0.0.0/0
Endpoint = 43.245.162.234:51820

And here's the docker-compose:

version: "3.7"
services:
  wireguard:
    image: masipcat/wireguard-go:latest
    container_name: wireguard
    sysctls:

    cap_add:

      - /dev/net/tun:/dev/net/tun
    ports:
      - 51820:51820/udp
    restart: unless-stopped

Fixed in latest. You will need to uncomment this line in your docker-compose.yaml: https://github.com/masipcat/wireguard-go-docker/blob/93a1aa175adcb0ed6a2867d44ffc98e6e5d2d4db/docker-compose.yml#L17-L18

Hm, it now gets a bit further along and then now fails with a different error.

Which OS are you using? I can't reproduce this error

Neurrone commented 4 years ago

I'm attempting to run this on a Synology. So this might not work because of an outdated kernel version. I'll test on another machine to see if I can reproduce.

Reproduced with docker running under WSL 2 on Windows 10 2004.
