I have a PC with Squid installed and working (although I have some problems withe the ACL: Squid is ignoring my ACL) and now I need all the Internet connections to go through it without configuring each browser on each computer in the LAN.
I tried this guide and all the computers in the LAN losed the Internet connection. I tried others iptables settings (just learned), without luck. I can't understand why. If I shut down the proxy all computer in the LAN lose the Internet access, so I don't think it is a hardware issue.
So, which could be a minimal configuration of iptables to accept every connection and redirect all to Squid?
Thanks beforehand.
