common/protocol: unknown address type: 0 #2507

Closed f0def closed 1 year ago

f0def commented 1 year ago

Hi all, thank you for the great product!

I want to run wireguard through vless tunnel (wireguard protocol is blocked, I want to hide it). Something like this:

When I run xray at Server1 and trying to connect to it from wireguard's client I see error in log proxy/socks: failed to parse UDP request > proxy/socks: failed to read UDP header > common/protocol: unknown address type: 0. What does it mean and what can be done to fix it?

And wireguard's client.conf

I don't think this would work, because on the inbound side you have configured to use socks5 protocol, which means the Wireguard client needs to open connection to your socks5 inbound(xray-core client) and perform handshake first, before asking it to forward Wireguard traffic to your remote server. Based on your config, it looks like the Wireguard client was simply treating your socks5 inbound as its peer server, which it is not. The error message here is expected, because the Wireguard client wasn't talking to socks5 inbound in socks protocol, and xray-core failed to parse the request header.

You need to use dokodemo-door https://computerscot.github.io/wireguard-over-xray.html

Thank you for responses. I've tried https://computerscot.github.io/wireguard-over-xray.html but faced with the fact that there is no traffic (I'm using port 51620 for wireguard). Maybe I missed something important?

Thank you for all your replies.

I figured out the reason. My problem was in AllowedIPs, it contains ::/0 at the end (https://github.com/XTLS/Xray-core/issues/2507#issuecomment-1702161379):

AllowedIPs = 0.0.0.0/1, 128.0.0.0/6, 132.0.0.0/7, 134.0.0.0/14, 134.4.0.0/16, 134.5.0.0/19, 134.5.32.0/22, 134.5.36.0/25, 134.5.36.128/27, 134.5.36.160/28, 134.5.36.177/32, 134.5.36.178/31, 134.5.36.180/30, 134.5.36.184/29, 134.5.36.192/26, 134.5.37.0/24, 134.5.38.0/23, 134.5.40.0/21, 134.5.48.0/20, 134.5.64.0/18, 134.5.128.0/17, 134.6.0.0/15, 134.8.0.0/13, 134.16.0.0/12, 134.32.0.0/11, 134.64.0.0/10, 134.128.0.0/9, 135.0.0.0/8, 136.0.0.0/5, 144.0.0.0/4, 160.0.0.0/3, 192.0.0.0/2, ::/0

I had to remove ::/0 and everything worked for me. I'm assuming that the problem was caused by the fact that I did not exclude the ipv6 address of my Server2 (it has both IPv4 and IPv6). https://computerscot.github.io/wireguard-over-xray.html was very helpfull.

I will close the issue.
