Hello,
I would like to know, is there any documentation on Mobile IP implementation
with VTUN. I found helpful site: http://mit.edu/kolya/www/mobileip/ . But I
am having problem with tun device recreating after handoff. It seems that
client side has problems with killing tun dev and starting new one.
