Can tun2socks support UDP? about badvpn HOT 7 CLOSED

shadowsocks/badvpn fork supports UDP directly

Checkout --enable-udprelay in tun2socks.c

It seems that direct UDP support is now possible w/ --socks5-udp parameter

You should build the current git version instead of 1.999.130, which is from 2015

Hi,
Tun2socks can support UDP through an udpgw daemon running on a remote host (on the remote side of the SOCKS). Please see details here, https://code.google.com/archive/p/badvpn/wikis/tun2socks.wiki
Currently tun2socks does not support UDP directly through SOCKS (the UDP feature of SOCKS). But note that the utility of such a feature depends on the SOCKS server anyway (e.g. Tor's doesn't support it).

Also I should emphasize that tun2socks was not intended for bypassing firewalls or censoring systems, and I have no plans to add any features specifically for that. It is just a way to transparently forward traffic through a SOCKS server, not much more.

Ok, tks.

if I use dante(support UDP) as the socks server, did I need udpgw daemon running on the same server? can you tell me the flow of forward udp by useing udpgw, I guess as follow :
tun--->tun2socks---->UdpGwClient---->SocksUdpGwClient-- ->socks_client--->socks_server--->udpgw ?

from badvpn.

The udpgw mechanism works such that tun2socks establishes a TCP connection to udpgw, through the SOCKS server. Udpgw sends and receives UDP packets using normal OS network access.

This is how it works, but I can't say what is the right solution for you. It may not be useful for your case in the first place (if you have no reasonable place to deploy udpgw).

Can anyone explain the --socks5-udp is official feature to let tun2socks to proxify UDP traffic? Thanks.
