Part III - Setting Up NAT
This section explains how to setup outgoing and incoming Network Address Translation (NAT). For
more information on outgoing and incoming NAT, see Diagram of Outgoing NAT, page 7-11 and
Diagram of Incoming NAT, page 7-12.
Outgoing NAT
To setup outgoing NAT, do the following:
1 From the Setup menu, choose General Setup. The General Setup dialog box appears.
2 Select the Enable Outgoing Network Address Translation check box. Click OK.
3 From the Setup menu, choose Outgoing Network Address Translation Setup.
4 The Outgoing Address Translation Setup dialog box appears.
Note: NAT is a useful tool that will be enabled the majority of the time on the remote side of
the wireless connection. It is rarely enabled on the base station. NAT is also useful to
have private networks connected to public networks (i.e., the Internet) without needing
a public IP address for every node. By using only one public IP address, NAT controls
who in the private network made a request to an address in the public network.
This translates the IP addresses from one side to another, hiding the private network
