Abstract
A correct port forwarding table in a gateway device, after reset of the gateway device resulting in expiration of at least one leased private IP address of LAN devices connected thereto, is disclosed. The present invention provides a port forwarding table which binds a port to be forwarded with the unique Media Access Control ('MAC') address of the LAN device which such port forwarding corresponds. In this way, if after a gateway device resets resulting in expiration of at least one leased private IP address of LAN devices connected thereto and if the LAN devices are leased new private addresses than prior to the expiration, the LAN devices will still receive correct port forwarding from the inventive port forwarding table of the present invention.
