I have in the past implemented this using netgraph and vnet but it was quite a log time ago and I forget many of the details The vnet jail was so that the gif tunnel effectively left from "another machine" (it was the same machine with a vnet jail) The reason was so that net failures were "one hop away" and therefore not so hard to work around. >> In the past, I have set up a similar link by tunneling ip over gif, but >> routing turned out to be intricate > what problems do you have with routing over gif?
