run tcpdump and see what kind of traffic you are having with the setup.
also, an exact network diagram (ASCII art), as well as exact
route/setkey/ifconfig setups (you may mask secret keys) are the
MUST for this kind of question.

you shouldn't need gif(4).
does not mention gif(4), because you shoulnd't need one.
