Configure Network Address
Translation (NAT)
Support is provided for Network Address Translation (NAT).
Network Address Translation is a technique which translates private
IP addresses on a private network to valid global IP addresses for
access to the Internet. Port translation (NAPT) allows more than one
private IP address to be translated to the same global IP address. Port
translation allows data exchanges initiated from hosts with private IP
addresses to be sent to the Internet via the router using a single global
IP address. A global IP address must be assigned to the WAN link
upon which NAPT is enabled for NAPT to work. The global IP
address will be assigned by the ISP.
To use NAPT, the private network addresses of the services that will
be available globally must be assigned:
