I went ahead and installed compass lite on a separate Rpi3, insterted the ThumbDV and installed ambeserver, and:
pi@TG9AOR:~ $ sudo systemctl status ambeserver@... -l
Feb 09 12:16:47 TG9AOR systemd: Started DV3000 Daemon.
So the setup now is
Rpi2 with DVMega(Repeater2) and ircDDBGateway -192.168.0.10-connected to Repeater 1 via 192.168.0.12 & Port 20011
RPi3 with ThumbDV and ambeserver-192.168.0.11-Listening on port 2460
Windows 10 Laptop with DummyRepeater(Repeater 1)-192.168.0.12-Connected to ambeserver via the Dongle Tab on DummyRepeater(DV3000 Network-192.168.0.11 & Port 2460) and connected to ircDDBGateway via the Network Tab(Gateway 192.168.0.10 & Port 20010) and this is where I am not sure, I left Local IP Address 127.0.0.1 & Port 20011, but I have no devices attached here to this laptop.
The DummyRepeater does not connect to the Gateway, it does not bring up the not linked status. When I press the Transmit button on the laptop, the ThumbDV does light up, but I do not pass any audio to the Gateway as I am connected to REF012E for testing and the audio does not come back to the laptop. I do see on the Gateway's log passing AMBE to port 20011 but I do not hear a thing on my laptop.
What did I miss??
