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.

Methods and apparatus for implementing NAT traversal in mobile IP

A method for communicating in a loadbalancing environment is provided that in a particular embodiment includes receiving a request packet from a network access server (NAS) to initiate a communication session. The request packet is then communicated to a tunneling protocol network server (TPNS) and a response packet is received in response to the request packet. The response packet establishes a tunnel that facilitates the communication session and that includes an identification element associated with the TPNS such that a data transfer associated with the communication session is executed between the NAS and the TPNS.
