Hello! My situation is very funy.
I want play World of Warcraft(on Win) with proxy(squid).

What's I have?
0. Debian5 without GUI. (192.168.0.51)
1. Squid proxy with PPTP connection to my provider with static IP(ppp0)
2. eth0(local net) and eth1(provider net) interfaces.
3. Windows7 PC (192.168.0.1)
4. Localnet over ~50 computers who use internet from proxy.

To play in world of warcraft with my situation, 2 ways:

1. use HTTP tunnel software like a sockscap, proxifiler etc.
2. use iptables, but i dont know what i need to do with iptables coz i newbie. (About ths way google say me new words to me NAT SNAT DNAT etc).

WoW need to use this ports 1119, 1120, 3724, 4000, 6112, 6113, 6114, 6881-6999 (TCP and UDP).

For 1st way I configured squid for this ports:
Code:
...
acl wow port 1119 1120 3724 4000 6112 6113 6114 6881-6999
http_access allow wow
http_access allow mypc
...
But tunneler soft say me:
"World of Warcraft Launcher.exe - 127.0.0.1:6881 error : Could not connect through proxy 192.168.0.51:8080 - Proxy server cannot establish a connection with the target, status code 403"

Ok, I googling again and see some post with answer: "You need to open "lo" conenctions" and some iptables rules
Code:
iptables -A INPUT -s 127.0.0.1/32 -i lo -j ACCEPT
iptables -A OUTPUT -d 127.0.0.0/8 -o lo -j ACCEPT
then iptables-save and dont work.

I think 2nd way can help me, but i dont know how to do this. Anyone can help me?
