Maybe I missed something......you wrote that they are five miles away, but no internet connection. Are you
saying that all RRC's are within the same LAN? If so, then no port forwarding is necessary at all. You address
the individual radio RRC's using their distinct internal IP number and the distinct set of ports if they changed. I
would think that you would not even have to change the port numbers either, since there is no need to separate
them for the purpose of port forwards.
If the radio RRC's indeed need to be reachable over the internet, then the above does not apply. Please clarify which
scenario is correct.
To answer your other question: since each radio RRC is addressable through its own internal IP number, there is no
difference from which control RRC connects to that particular radio RRC. they can alternate the connect without any
change being made at the radio side, but can not connect simultaneously.
I hope this helped clarify your questions. Some of your terminology confused me, since you were talking about ports
and static IP numbers. You meant static internal IP numbers, which are anyway necessary for radio RRC's. Port
changes are only necessary if you need to reach the radio RRCs over the internet.
