firewall2 / caching proxy question

Hi, I am currently running SuSEFirewall2 on my machine and an trying to add the 'oops' caching proxy to my network. I would like to be able to use the transparent mode in which I don't have to set a proxy for all browsers. What I am trying to do is to redirect all requests with a destination port 80 to port 3128 of my gateway/fw machine. My outside world interface is ppp0 and my internal network interface is eth0. I need help in 1. the creation of the iptables rule. 2. figuring out where to put this rule in the context of the firewall2 settings. Thanks, Avi -- Avi Schwartz Get a Life, avi@CFFtechnologies.com Get Linux!
