Hi I have an HF transceiver based on a Pi4 and radio berry. It works fine on my LAN with SDRConsole but I am unable to connect to it from the internet.
On my LAN I have fixed the IP address in my router (via DHCP) , I have a fixed IP and I have port forwarded external port 1024 (I have tried several others) to the pi but I am unable to connect with SDR Console. I have had no problems with access via SSH with port forwarding.
Does anyone have any ideas as to what to try? I presumed it was a port forwarding issue but maybe it is something more fundamental?

Regards Richard

The UDP packets need to be delivered with low latency. Not something the internet will help fix. You could try a VPN but I don’t think the IQ data will be useful with delays and drops from the internet

your better off using vnc or rdp to console in and pipe audio or whatever not the raw IQ?

Thanks for your comments. I hadn't realised how many UDP ports SDR Console uses to talk to radios. I used wire shark to monitor traffic to the radio on my LAN and forwarded all the ports I could see in use to the radio. I could then operate it from the internet but the audio quality was not good, especially on transmit, probably due to bandwidth / latency problems.
I also have an RSP1A listening to QO-100 on 739 MHz this is connected to a RPi4 with SDR Play server which talks to SDR Play client over the internet but this has the option of using an audio connection rather than full IQ and the audio quality is good with this (SDR Play client though is nowhere near as good as SDR Console). I was hoping to have a full duplex QO-100 transceiver, with remote operation, using my RPi/radioberry transceiver (with DXpatrol up / down converters from 28 MHz) + the RSP1A for listening during transmission. It does all work now but the quality is not good enough. I think I will try using a VNC set up.
