Methods and apparatus for establishing communication between a Mobile Node and a Home Agent are disclosed. The Home Agent receives a registration request packet from the Mobile Node, the registration request packet including an IP source address and a Home Agent address. The Home Agent then detects from the registration request packet when network address translation has been performed. When it has been detected that network address translation has been performed, a tunnel is set up between the Home Agent address and the IP source address.

Why it's free to use
- Filed December 23, 2002 and granted November 13, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 23, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 23, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
