How does one set a rule in IBM's Internet Secure Network Gateway to allow Notes 4.1.4 replication?

[Nestor & Christine Navarro <nnavarro @ pathcom . com>]

I am having setting up the IBM's firewall the "Secure Network Gateway"
to allow a machine in an internal network with Lotus Notes 4.1.4 to
replicate (or even at the moment to talk) to an external machine over
the Internet.  All I know is to open up PORT 1352.  Part of my problem
as well is my internal network also has unregistered IP addresses.  So
how do I handle Name Address Translation?

If anyone can be of any help, I would gladly appreciate it.

Thank you.
Chris.
