How to redirect browsers with static proxy settings in iptables?

["Todd Landfried" <tlandfried@xxxxxxxxxxx>]

I'm new to this firewall stuff, so any assistance would be greatly 
appreciated. I've RTFM as much as I can, but nothing seems to fit this 
situation exactly. Maybe I'm not asking the questions correctly in Google.

I have a Linux 7.3 (2.4.20-28) server with two NICs. One is eth0 and 
connects to the router. The other is eth1 and connects to the switch that 
connect the computers in the house. We have a couple of laptops that have to 
have static proxy settings in the browser for work, but it's a royal pain to 
have to go and unclick the "use proxy" settings all the time. I'm being 
pressured to find a solution--if you know what I mean.

Let's say the proxy settings are:

IP: 68.152.65.65
Port: 80

Let's say the internal network is 10.1.0.x. I've also installed squid 
(2.4.stable6) and I think I have that correct, but it's not working. I may 
be missing some component, but I'm not sure.

How do I create a rule that will route the browser traffic through the linux 
box without having to uncheck the silly checkbox everytime she comes home?

Any solution or guidance would be appreciated.

Thnks

Todd
