NightHawk
Do any of the nighthawk series allow for one port to be accessed from an external IP to one internal device?
Not what I was hoping for but that'll do.
Forward one port on the public IPv4 address to one IP4 address on the LAN port - yes.
Limit the access to just a single IPv4 address from "out there" - no.
No idea if this is what you wanted to hear.

So retry the query 8-)
Do you expect something like these (misleadingly named) DMZ LAN ports where all Internet incoming connections are going to? Some (not all,y expensive X10/R9000 doesn't - that's why I forget about it sometimes) Nighthawk models support it:
How do I set up a default DMZ server on my Nighthawk router?
Actually I have an SQL server providing service to my small business and I want to lock down a specific port to a single internet address.
In my understanding, there is no such user accessible firewall rules available for WAN->LAN. A big mistake in all Nighthawk WiFi Router design... I don't get it why a "service blocking" or a limited (nicely said) OpenDNS based family security has priority over a simple configurable firewall.
