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 Brocade Mobility 7131N-FGR 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 Brocade Mobility 7131N-FGR Access Point:
1. Select Network Configuration -> WAN -> NAT from the Brocade Mobility 7131N-FGR Access
Point menu tree.
2. Configure the Address Mappings field to generate a WAN IP address, define the NAT type and
set outbound/inbound NAT mappings.
