Situation:

2 network locations, connected by using Bordermanager VPN Site-Site
over the
internet.
Each location has 1 Bordermanager server, 1 Netware file&print server
and 1
Mailserver. The Bordermanager server has 2 NIC (1 to the private and 1
to
the public). Public interfaces have NAT Dynamic enabled.

My question:

How can we make a connection from the internet (SMTP) to the internalmailserver passing NAT. Bordermanager does not support PAT.......

Please help

Thanx
