ipnat expands ppp0/tun0 to the ip-address ppp0/tun0 has AT THE TIME when you run ipnat,
so you have to run ipnat AFTER you have gotten your dynamic-IP.

Try this config, which works for me.

/etc/rc.conf
ipnat=NO

WIth ppp (tun0)
	/etc/ppp/ppp.linkup
	MYADDR:
	 shell ipnat -CF -f /etc/ipnat.rules

	/etc/ppp/ppp.linkdown (tun0)
	MYADDR:
	 shell ipnat -CF

Or, with pppd (ppp0)
	/etc/ppp/ip-up (do a chmod +x)
	#!/bin/sh
	ipnat -CF -f /etc/ipnat.rules

	/etc/ppp/ip-down (do a chmod +x)
	#!/bin/sh
	ipnat -CF
