Sorry, would have responded to the original post, except I can't find it.

I used to have IPCop and had the same problem.  When you set up IPCop to
port forward, you need to make another change on another page of the
interface before it will work.  Unfortunatly I am at work and my IPCop
machine is sitting on a shelf powered down at home, so I can't look up
which page it was that I used.  I would persevere with the IPCop interface
though.

Will.
