Found the problem, but most bizarre. Don't know if anyone else has experienced the same.
Two problems found: one with the modem/router, the other with RRC-1258 Remote box.
In the modem/router all the port forwarding was corrupted. Ports forwarded on wrong computers/devices. Some computers such as TRX Manager running on my main PC was removed from my PC and reassigned to an X-Box! After I reassigned and reconfigured the modem/router, I got TRX-Manager to work. But Remote rig would not.
I originally had the RRC-1258 remote configured to bypass the firewall, so it was DMZ'ed. I couldn't get port forwarding to work, but DMZ allowed the system to work (yes I know it's not the best configuration but it works). So when I tried to set the DMZ option on the modem/router after the problem was discovered, the modem/router said the device needed to be using DHCP. Using Microham set-up manager, I confirmed that the DHCP box was ticked off. Tried to configure the Modem/router and still no go. Went back into set-up manager, disabled the DHCP and tried the modem/router again. Still no go. Went back with set-up manager, ticked off the DHCP box and now the modem/router allowed DMZ configuration and now remote-rig works again!
So. What would have caused the modem/router to reconfigure, and why would the software in the Remote-rig box get corrupted?
The RRC-1258 Remote box is normally off (no DC voltage applied) when I am not using the Remote. So a voltage spike on power-up?
