5.2.1 Configuring Network Address Translation (NAT) Settings

Network Address Translation (NAT) converts an IP address in one network to a different IP address or
set of IP addresses in another network. The access point router maps its local (inside) network
addresses to WAN (outside) IP addresses, and translates the WAN IP addresses on incoming packets
to local IP addresses. NAT is useful because it allows the authentication of incoming and outgoing
requests, and minimizes the number of WAN IP addresses needed when a range of local IP addresses
is mapped to each WAN IP address. NAT can be applied in one of two ways:
• One-to-one mapping with a private side IP address
The private side IP address can belong to any of the private side subnets.
• One-to-many mapping with a configurable range of private side IP addresses
Ranges can be specified from each of the private side subnets.
To configure IP address mappings for the access point:
1. Select Network Configuration -> WAN -> NAT from the access point menu tree.
