The NAT Screens
This chapter describes how to configure Network Address Translation (NAT) rules and how to enable or
disable application-layer gateways (ALG).
NAT Rules
Use the [NAT] tab to configure the following settings:
•
1-to-1: The simplest form of NAT for point-to-point translation of IP addresses.
•
Multi 1-to-1: This form of NAT allows you to map multiple public destination IP addresses of incoming
traffic to multiple private IP addresses within the local network and vice versa. These rules can also
allow you to map a source IP address from your local network to outgoing traffic.
•
Port forwarding address translation for incoming traffic on the WAN interface.
The following table describes the basic tasks you can perform from the [NAT Rule] tab.
