4.10 NAT Configuration
To configure the address translation function, click on NAT in the Configuration section of
the main menu. There is independent IPv4 and IPv6 NAT configuration since there is dual
stack IPv4 and IPv6 implemented in the router. The NAT item in the menu on the left will
expand to IPv4 and IPv6 options and you can click IPv6 to enable and configure the IPv6
NAT – see Figure below. The configuration fields have the same meaning in the IPv4 NAT
Configuration and IPv6 NAT Configuration forms.

The router actually uses Port Address Translation (PAT), which is a method of mapping a
TCP/UDP port to another TCP/UDP port. The router modifies the information in the packet
header as the packets traverse a router. This configuration form allows you to specify up to 16
PAT rules.
