What TCP ports need to be opened up on a router for ASIAIR+ to work?

I am using a BerylAX to extend the range of my home network to my telescope so I can use it 100+ yards away from my home.

I have established rules for port forwarding for the following ports:
4350, 4360, 4400, 4410, 4500, 4700, 4710, 4720, 4800, 4810, 9624

I can see ASIAIR from my iPad, but it hangs indefinitely on me trying to connect to it.

For the record, this is the diagram of the setup:

What port am I missing? Seems I am very close to getting this to work.

I see you're trying to connect devices across different subnets (192.168.8.x and 192.168.1.x). Why are you doing it that way?

This is how BerylAX sets up the default LAN subnet, I am not sure how can I make it use the 192.168.1 one if it's not the main router

Update: forced the subnet to be the same, it fixed it!
