It is the ESP form of IPSec and, you are correct, it does not use a
port.  You would simply specify the protocol, e.g.,=20
iptables -t nat -I PREROUTING -d 129.37.0.111 -p 50 -j ACCEPT
You may find it helpful to run through an iptables tutorial.  I found
Oskar Andreasson's (listed on the netfilter.org site) to be very
helpful.  There is also a slide show on using iptables in the training
section on http://iscs.sourceforge.net
Good luck - John
