IPSec normally uses AH and ESP which are protocols in the same layer as
UDP and TCP. The protocol numbers are 51 and 50. If a firewall blocks
all protocols besides UDP and TCP, and filters those protocols by ports,
you can only use UDP encapsulation. I never tried to do this with FreeBSD,
though. Dunno if the kernel can do that. I didn't find such a thing in
the setkey manpage on 5.3. It mentions TCP, though.
