HTTP Redirection to Proxy

[Linuxian]

OK, I've been digging through every news group and google hit I can
find but nothing seems to help with this issue.

I need to have my R55 CP Firewall redirect all http traffic it receives
on port 80 to my proxy server that runs on port 3182. I've read
snippets about using UFP services etc but nothing concrete.

If anyone can provide any information, or a link, or a filename for the
relevent documentation, I would greatly appreciate it.

If anyone has actually made this work, PLEASE LET ME KNOW!!!

Arrrgghhhh, It's hard to believe that I can do this with a single line
in a Linux box running iptables but my mega-gazillion-dollar Checkpoint
firewall can't??

Someone please help.....
