Open two more colon "To Address", "To Ports" and find to which local IP:port you translating your 76.212.90.etc
It's going to the proper IP addresses and ports. As I said, it was working and I haven't changed that. And I can reach the second server from a browser on the LAN using the local IP address, and services from outside can access through the WAN without issue. It's only when I try to access using the domain name (and DNS) from within the LAN that I have a problem. And, again, it appears that the problem started after I upgraded to 6.42.3.
Edit To Add: I'm posting the picture, but I'm posting it from my own server so that I can take it down once the issue is resolved:
