The Network Interfaces in the Routing And Remote Access console
You can specify specific services that are available on your internal network and map ports
and protocols to the servers providing that service across the NAT boundary. For example,
if you have a mail server at 192.168.10.5, you can configure port mapping on the public fac-
ing network interface to forward all SMTP packets (port 25) to the server at 192.168.10.5, as
shown in Figure 3-37. However, this port mapping capability should
not
be substituted for a
firewall.
