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:
