Open dogfight360 opened 7 years ago

dogfight360 commented 7 years ago

Listen to loopback IP:127.0.0.1 TCP and UDP work properly

but Listen to loopback IP:127.0.0.2 or 2-255 TCP is working properly, UDP can not be transport

send Application.UDP------>gotun2socks------>server------>target recv Application.UDP--x---<gotun2socks------<server------<target

The packet passes through the server and returns But there is no return from the gotun2socks to the Application

@wu360463231 I just fixed a bug in gotun2socks's UDP processing, which may cause the problem you described. Please update the code and test again and let me know the result. Thanks.

UDP Still does not work Socks5 listen to loopback IP: 127.0.0.2 or 2-255

I tried to listen socks5 proxy on 127.0.0.2. UDP tunnelling worked fine.
