FIELD DESCRIPTION EXAMPLE
NAT Press [SPACE BAR] and then [ENTER] to select Full Feature if you have

Mapping Set When Full Feature is selected in the NAT field, configure address mapping
sets in menu 15.1. Select one of the NAT server sets (2-10) in menu 15.2

When SUA Only is selected in the NAT field, the SMT uses NAT server set 1
in menu 15.2 (see the NAT chapter for details).

Metric The metric represents the “cost” of transmission for routing purposes. IP
routing uses hop count as the cost measurement, with a minimum of 1 for
directly connected networks. Type a number that approximates the cost for
this link. The number need not be precise, but it must be between 1 and 15.
In practice, 2 or 3 is usually a good number. 2

The following figure uses sample IP addresses to help you understand the field of My WAN
Addr in menu 11.3. Refer to the previous LAN and WAN IP Addresses figure in the web
configurator chapter on LAN setup for a brief review of what a WAN IP is. My WAN Addr
indicates the local Prestige WAN IP (172.16.0.1 in the following figure) while Rem IP Addr
indicates the peer WAN IP (172.16.0.2 in the following figure).
