Apparently this is the missing ingredient in connecting my Ark Cluster Server setup.  Is there a way to make this happen without buying a new router.

Not that I know of.

Couple of google searches, also came up with the synonyms: NAT Reflection or NAT Hairpinning, you could check your router for those. However if the answer is still nope, then yes looks like you need router.

This function needs to be done on the device which does NAT to the outside world, usually your router.

 

you could setup pfsense in a docker.  free router.  it supports nat loopback hairpinning.  Im in the same situation, but havent pulled the trigger yet.
 

if your current router supports "bridge mode" to set a lan port to bypass the primary router, even better.
My ISP router supports bridge mode.  Sets Lan port 1 to get a second public IP address, and bypass all the junk of the ISP router to plug in your own.
