The Local WAN IP Address is used to configure a NAT public address range consisting of the Local WAN IP Address and all its ports. The public address map list is named Easy-PAT List and the port map list is named Easy-Servers.

These map lists are bound to the Easy Setup Profile. See Binding Map Lists and Server Lists on page 11-23.
