[ILUG] setting up a transparent squid proxy.

[Darragh]

Hello there,

I'm trying to get my head around something at the moment and I'm hoping
someone can possibly shed some light on my thought's here.

I want to set up a transparent proxy.  It's actually something I'm going
to have to replicate in work to a larger extent and I want to learn how to
do it here first where it's not going to cause any down time.

I think I have the squid.conf file configured enough to give me the
feedback I'll need when I get traffic directed through it but I'm having a
bit of a problem understanding exactly how I go about directing traffic to
that machine.

The setup here is as follows:
machine on 192.168.2.6 is acting as the dhcp server.
I want this machine to also act as the squid server.
It has only one ethernet interface of relevants here.

so basically, I need to determine a way of sending all traffic to that
machine without configuring any proxy on the client side.

The router that I'm using doesn't seem to have any decent internal port
forwarding capability if any at all so it looks like I need to use the
same box to handle this as well.

Is this at all possible?

I was thinking that if I set the gateway to 192.168.2.5 i.e. the linux box
instead of the router at 192.168.2.1 perhaps I could get all traffic
directed through that machine and use another package to handle that.

Any suggestions welcome.

I'm using OpenSuSE 10.3.

Thanks
