RRC-1258 connects on local network, won't connect via ddns.remoterig.com

[AA4LR]

I've recently gotten a set of RRC-1258 remote rig boxes, and have successfully connected them to a pair of K3 radios. The remote radio is a plain K3, the control radio is a K3 with a KIO3B.

Connected to my local LAN, I can successfully connect from the control to the remote, using the SIP address of the remote (192.168.1.64). Works as expected.

If I re-configure the control to use the xxxxxxxx.ddns.remoterig.com address as the SIP address. It will not connect. I hear three tones (beep, beep, beep) in the headphones of the control over and over. I even tried to move the control unit 100 miles away so that I was on a different network. Same result.

Any suggestions? I copied and pasted the Own host name from the remote to the control SIP address directly, so I'm sure I've got it right. The Microbit DDNS status appears to be correct.

I would like to get this working.

Having been given a tip by the ham I bought the boxes from, I found that my issue was my firewall settings weren't properly configured.

I also found that my UDP ports were set to the old values 12000,11000,5060, even though I had upgraded to the v2.95 firmware.

I re-assigned these to new port numbers.

The hardest part was figuring out the best way to pass these UDP ports through my ATT router. The IP Passthrough worked, but it completely exposed the RemoteRig device to the public internet. I ended up defining four "gaming" services to map the UDP ports, and assigned them to the RemoteRig local IP. That worked.
