This remote control setup i basically an internet based extension of the separation cable between radio and front panel (e.g IC-706) allowing the operator to connect his front panel via an interface to the remote radio using virtually any internet connection.
It uses SIP, which is IP-telephony standard, to make the connection between the interface boxes on each side of the network. It will negotiate via a STUN server so both sides know the external IP addresses used if NAT routers are involved.
UDP ports used are:
5060 = SIP, standardport SIP. If you already use IP telephony this *might* be a problem.
11000 = RTP, Sound
12000 = Datachannel, Serial comms between front panel and TRX.
So, here is what you need to do:
Get a ICOM separation cable. Cut it in half. Connect each half of the cable to RJ45 connectors using these diagrams:

If everything works, then the interface boxes need to be configured (assuming firewall / port forwarding issues have been solved)
Configuration will look like this (page in Swedish for now)
