	You will need this line along with the same line for tcp traffic.

	ALso make sure you are allowing firewall traffic (in this order):

	divert natd ip from any to any
	allow tcp from any to 192.168.0.10:6112-6119 
	allow tcp from me 6112-6119 to any
	allow udp from any to 192.168.0.10:6112-6119 
	allow udp from me 6112-6119 to any

	I don't know if the punch_fw option in natd will help you much
	(not sure on that point).
