Final Thoughts / Conclusion:

The radio setup parms are pretty well covered on youtube. IE: CI-V setup as well at the Network parms.
Remember to use static IP's for your radio's that will ease in the firewall/router setup.

Your Router config will no doubt look different then my Netgear setup but the theory is the same.
Rule file then Port Forwarding those ports to each radio's individual IP addresses.

Just some added Radio/Router info:

Control Port  (default 50001)
Serial Port    (default 50002)
Audio Port   (default  50003)

You can change these ports to what ever you want to, (see the previous pic's I used for using two radios)
Likewise match those port setting on your Router.
Note:  you must pass all 3 ports through your router in order for this to work!

The RS-BA1 instructions are on Youtube.

This isn't all that easy, so feel free to holler for questions:

good luck and 73.
