I currently run srelay (a socks proxy) on my router at port 21 (http://www.linksysinfo.org/forums/showthread.php?t=55755). This srelay is actually set up in a chain, so that all traffic sent to this proxy is forwarded to another socks proxy server.
I want to configure my tomato (asus 520gu) router so that all traffic from the LAN side (wired ports) is redirected to the local socks proxy at port 21. In other words, I want all devices connected to a the LAN ethernet side of the router to send all traffic to the local socks proxy at port 21.
Any suggestions on how to do this?
