Ok recompiling now. Hopefully it works fine. I'll report back.

Thanks.

Actually, you can apply a patch to src/sys and recompile your kernel
with IPSEC_NAT_T options.
Patches are available here:
http://people.freebsd.org/~vanhu/NAT-T/


You can also try to play with Perforce's branch, but it is still work
in progress to have a cleaned up version of PFKey interface (it may
work, but I just started to set up some testing hosts).



To answer the question some people may ask in this thread: the whole
patch should be included in TRUNK as soon as PFKey cleanup will be
done (which means "implemented + heavilly tested + reviewed").



Yvan.
