Seeking help for Redsocks setup

alberto · 2020-12-14T22:34:18.365Z

Hi,

I have a GL-MT300N-V2 and I would like to create a setup using Redsocks to route all traffic from the LAN port to a SOCKS5 proxy server situated in the WAN. I am not very familiar with iptables and I am having troubles finding the right configuration. Any help would be very appreciated.

TIA,

I don’t have experience on this. Can you do according to

gist.github.com

https://gist.github.com/afriza/1097210

redsocks.conf

base {
        // debug: connection progress & client list on SIGUSR1
        log_debug = on;

        // info: start and end of client session
        log_info = on;

        /* possible `log' values are:
         *   stderr
         *   file:/path/to/file

Hi alzhao,
thanks a lot for the pointer. I tried the configuration on that page, but somehow it doesn’t work on my setup. I’m pretty sure there must be something wrong I’m doing or there’s something different in my setup that is preventing it to work, because the information on the link you posted are very sensible.
