NAT Commands
ENABLE IP NAT
DISABLE IP NAT
Enables/disables NAT (Network Address Translation) for this profile. With NAT enabled, only
one IP address is used when communicating with remote sites via the external network. The
real IP addresses of computers on the local LAN are never revealed to remote sites.
Default: Enabled.

visible to the external network.
ADD IP NAT { UDP | TCP } port ipaddress

an SMTP server (for e-mail), set TCP to port 25 and enter the IP address of the computer that is
to function as the server.
