Chapter 24 Mobile IP Administration

Mobile IP administration has been enhanced in the Solaris 8 4/01 release. The following information supplements information on Mobile IP administration that is in the Mobile IP Administration Guide.

For the most current man pages, use the man command. The Solaris 8 Update release man pages include new feature information that is not in the Solaris 8 Reference Manual Collection.

Reverse Tunneling and Private Addresses

Mobile Internet Protocol (IP) enables the transfer of information to and from mobile computers, such as laptop and wireless communications. The mobile computer can change its location to a foreign network and still access and communicate with and through the mobile computer's home network. The Solaris implementation of Mobile IP supports only IPv4.

In the Solaris 8 4/01 release, Mobile IP enables you to set up reverse tunnels. By setting up a reverse tunnel from the mobile node's care-of address to the home agent, you ensure a topologically correct source address for the IP data packet. By using reverse tunnels, you can also assign private addresses to mobile nodes.

For an introduction to Mobile IP with reverse tunneling and the use of private addresses, see “Overview of Mobile IP” in the Mobile IP Administration Guide. Chapter 2 addresses the Solaris Mobile IP implementation of these new features.
