Can you describe what standard is used to change the IP address of the mobile router's rf link back to the bus depot? I have a similar problem involving a mobile LAN, not just a single mobile node, which is what Mobile IP.
designed for. Moving a whole LAN around means your gateway router external interface's IP address is always changing.
For our solution, our developers hacked the Linux Mobile IP to support IPSec for registration (of course, the advertisements are still broadcast in the clear). What I'm not clear on is how they maintain routing updates and integrity (I haven't seen that part of the code yet). And my talks with Cisco indicate they're toying with different methods of doing mobile adhoc routing, but this scenario is really mobile infrastructure routing where the "access point" moves around from cell to cell.
Any po> I can help, I have a great Cisco based solution for you.
