Gary,
Are you still having issues with this setup?
Don't know about the purpose of the Extern IP/Host, manual says it has something to do if you have a static IP, but you don't so it shouldn't be an issue...
I haven't had any issues connecting from outside after I got the right control program for my radio. I'm using Commander to control my IC-746Pro.
The only setting that will have to change upon where the remote (do you mean Control RRC?) is located is that the firewall will have to have appropriate and active forwarding set up for the 4 ports if you're outside of the firewall.
If you are experiencing problems from hotels or other corporate networks, it may be that the firewall has some funky rules blocking some port traffic - particularly if some of the ports are "usually" used for high-bandwidth games or VOIP products. If you have remote admin privileges enabled at your router, you can try to change the ports used for SIP, Audio, and Control along with the corresponding firewall rules and see if that works, but I would only try that if you can actually log into your Radio RRC router because all of that traffic uses port 80 which should be wide open on any network connected to the world. If you can't log into your Radio RRC, there's something else going on - maybe your ISP gave you a new IP and you should be using DynDns
, or the firewall rules aren't working as you expect.
