RE: [squid-users] Single NIC transparent proxy

Hi Robert,

If your Juniper router has WCCP support then you can consider using it for
transparent proxying. The FAQ has a section on WCCP.

Subject: [squid-users] Single NIC transparent proxy

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.
