How to change admin and webmail ports?

Hi,

I am running a ipcop fire wall and it uses port 81 for its admin interface. It won't let me port forward any ports to port 81 because it is using it.

How can I go about changing the port that is being used by web mail, and admin?

I was going to just edit the httpd.conf file for the admin apache and see if that works.

Thanks for any help
