Can someone help me out..I'm trying to get an understanding of setting up mobile IP. I read the documents and it seems I would need a home router and a foreign router...My question is can I use one router to accomplish mobile IP..Who controls the foreign router...Would I need the ISP assistance in establishing virtual internet connection....Could I use a 2500 series cisco router to accomplish this task...I guess basically what would I need to start with and what devices would I control.....
