Raymarine forum

Hello,

I have in my boat 2xWifi networks, one where the ES75 is connected, and another for pads and phones. The networks are connected together via a router with NAT.
When I have my pad on the 2. network its not able to find my ES75.
I think that the reason is that some of the ports in the router is not open.
What ports is the RayControl app using to communicate with the ES75?

HI dreuf
Thankyou for your enquiry.


The detection is implemented using a mechanism called Avahi, which works on port 5353. It looks like the remote control TCP sockets work on port 50000, and the RTSP stream of the MFD image is on port 8554, at least in LH3.

I hope this helps?
Regards
Derek
