Okay. I think I have it working again. I noticed after the hard reset, the DHCP ending Address was different. I reassigned the address of the server within the specs, changed the NAT host address to match the new server address and it started working again.

I am guessing that something may have been corrupted in the TC and going through and matching up all of the addresses again did it...or perhaps it was on the ISP and cleared up by itself!

Still odd that it worked fine for over two years without a single glitch.
