Let me explain my setup before I go into any details I have a squid proxy with network A(192.168.1.0) connecting through eth1 and network B(172.16.29.0) connecting through eth2. the Interface going out to the internet is eth0. The Proxy had been working just fine when only network A was connected however I needed to add network B to the mix. Installed the card, added new network to the acl and brought the interface up. Now when I try connecting to anything with my client machines on either network I either get Connection Refused(error received from squid) or the Connection Times out. When I drop eth2 so network B is no long connected network A is again able to connect. So my question is what would be causing this and how can I fix/get around it. At the moment I have no iptables rules in affect. I have Squid 3.0 installed.
