Abstract
A guest station on a foreign network is provided IP access by the foreign (i.e., hosting) network without changes to the guest station, including settings for IP address, next-hop-router (gateway), and netmask. An access router automatically detects guests and their home-IP-address and assigns a local care-of address to every guest. For outgoing traffic, the router replaces the guest's original/home IP address with the care-of address, and the reverse is performed for incoming traffic. IP traffic may thus be initiated, and responses received at the temporary current location without having to change its IP address.
