transparent proxy w/ slackware 10.2

hey. i want to put a transparent proxy between the network and the DSL
router. I'm using slackware 10.2 with kernel 2.4.31. I *kind of* know
how to setup iptables to -j REDIRECT the port to localhost port
8080(proxy) but I need a bit of guidence. Im like 17 and not a Linux
guru so I need a bit of help. The bridge is set up and i'm running
raid0 on two IDE channels. And by the way what is ip forwarding
(/proc/sys/net/ip_forwarding) and what spesifically does it do?

If you have two or more network cards in your box and want to route
traffic between the different nets (ie your box is a router/gateway),
you have to "echo 1 > /proc/sys/net/ipv4/ip_forwarding" to enable this
function.
