Please help me with this problem... I am running Ubuntu hardy server with squid 3. I have searched high and low for a tutorial on how to configure squid as a transparent proxy with a single NIC. Every tutorial I have seen (hundreds) assume that the proxy is also the router sitting with 1 NIC outward facing and 1 NIC inward facing and they have you set up the squid cache with the firewall being set for NAT. I can find no tutorial for my situation and my beating on it has gotten me nowhere. My environment is as follows. I have a Juniper router/firewall combo sitting as the "true" default gateway on my network (x.y.z.1). My squid proxy will only have a single NIC and will be sitting on x.y.z.2 and all of my client PCs are pointed to the .2 address as their default gateway. I DON'T need NAT enabled on the cache box in this scenario but it needs to be transparent and it needs to forward ALL traffic to x.y.z.1. There is literally no tutorial out there that I have found to handle this scenario. Robert
