Abstract
An inventive Network Address Translation (“NAT”) device and method for automatic port forwarding whenever said NAT device detects that only one Local Area Network (“LAN”) IP address has been leased by its DHCP server is disclosed. Under this condition, the inventive NAT device automatically configures all ports to be forwarded (except those that may be reserved for applications running in the inventive NAT device), to the single leased LAN IP address. This minimizes, if not eliminates, the conventional address configuration required when a NAT device is added to an existing network.
