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.
2.
Configure the
Address Mappings
field to generate a WAN IP address, define the NAT type
and set outbound/inbound NAT mappings.
WAN IP Address
The WAN IP addresses on the NAT screen are dynamically
generated from address settings applied on the
WAN
screen.
NAT Type
Specify the NAT Type as
1 to 1
to map a WAN IP address to a single
host (local) IP address. 1 to 1 mapping is useful when users need
dedicated addresses, and for public-facing servers connected to
the access point.
Set the NAT Type as
1 to Many
to map a WAN IP address to
multiple local IP addresses. This displays the
mappings
button in
the adjacent Outbound Mappings field. This button displays a
screen for mapping the LAN IP addresses that are associated with
each subnet.
Define the NAT Type as
none
when routable IP addresses are used
on the internal network.
