[Shorewall-users] Problem redirecting

[Ashleigh G. <ash...@dc...>]

Whenever I try and use a redirect rule, I get the following error when 
restarting the firewall:
kmod: failed to exec -s -k ipt_REDIRECT, errno 2

An example rule that I am trying to use is:
REDIRECT    loc       3128   tcp   80    -
I've also tried:
REDIRECT    masq       3128   tcp   80    -

But the error is always the same. Uncommenting out the REDIRECT 
statements lets the firewall restart properly, and all is fine. This is 
running on a linux server, which is connected to a cable modem, and also 
an internal network. I want to sue the REDIRECT statement to set up a 
transparent proxy. It looks like a kernal/modprobe error, but I was 
wondering if anyone else has everr come across this error before?

Info about my setup:

I am running Mandrake 9.0 with security updates, kernal version is 
2.4.19-16mdksecure.
