	Sometime late August or early September, changes to IP or UDP code
	broke the IPSEC proxy.  ipnat lists:

	MAP    500   <- ->   500   [ 500]
		proxy ipsec/17 use 1 flags 0
			proto 17 flags 0 bytes 1044 pkts 4 data YES size 328
		IPSec Proxy:
			ICookie 335d631f180abf04 RCookie 0000000000000000 (Not set)

	e.g. set up an IPNAT rule(1) on a gateway machine and try to set up
	an MSWin L2TP connection over it.

	(1) map pppoe0 -> 0/32 proxy port isakmp ipsec/udp
