I've got a squid server running transparently behind my router. Everything works great with it. I now want Tomato to forward all requests for unspecified MAC addresses to my squid server. I'm running Tomato 1.25.8515 - Victek RAF. I've tried following this post to get it to work. http://www.linksysinfo.org/forums/showthread.php?t=60533 using these lines: iptables -t nat -A PREROUTING -m mac --mac-source YY:YY:YY:YY:YY:YY -p tcp -j ACCEPT iptables -t nat -A PREROUTING -p tcp -j DNAT --to-destination ZZZ.ZZZ.ZZZ.ZZZ (zzzzzzzzzzzzzzzzz) being my squid server. It doesn't work. Setting the squid server manually as a proxy in my web browser settings works - but I want Tomato to handle redirects. Any ideas?
