	I forged ahead, and I get "The WAN IP address may not be used in a Server NAT entry" so I guess that's not the answer. Seems like a bug then, that "interface address" behaves the same as "all WAN IP addresses" in NAT rules?

	I started to look at firewall rules to block the unwanted port redirections.  Unfortunately I'm not sure that will work either.  The logged packet has a source of the remote IP, and the destination is the LAN IP.  How would I set up a rule to block incoming traffic for just one WAN IP?
