Our little office network consists of a DSL router, and one subnet with about 15 hosts.
One of the hosts is running Squid, and it all works fine with the browsers on the clients set to use Squid.
Of course, the users can simply choose to not use a proxy and can surf the internet directly. This is what I'm hoping to change.
What gets me is how to set up my DSL router to allow only the machine running Squid to request web pages. Or should I be looking at the switch for a solution.
I guess what I really need is someone to help me understand the mechanism of how to tackle the problem more than a HOWTO.
The Router has a web interface. It allows me to black and allow traffic from and to certain machines based on which port the request is sent on. Sometimes it takes the value of 0.0.0.0 as the IP address. Would this mean that it allows all traffic on that port?
there's not much in the way of documentation for that router, but basically you want a blanket deny rule for 0.0.0.0 outbound on TCP/80 and an allow rule for your proxy server. If it came with a manual or .pdf on a cd-rom etc, then it should detail how to do this...
