HL2 port forwarding ?

[Pencoys]

If I want to access my HL2 from outside the local network i.e. other side of
the modem/router what ports should I allow through ?
Thanks, Mike

Hi Mike,

port 1024 for udp is  needed, there maybe other issues. Discovery is unlikely to work, some software allows you to fix the ip address but the typical local ip address will not be visible outside your network so some other magic has to happen to route to the HL. I think the most common way to achieve this is by setting up a vpn. 

I believe there are a number of projects around trying to make this simpler, there is a websdr interface to the HL and the websockets interface to spark is another approach.

Hi Mike.

If "remotely operating" the Hermes-Lite is your objective, there are other ways to do so that are less demanding in terms of network demand then port-forwarding port 1024 and transfer all OpenHPSDR-protocol related traffic to your remote location.

I myself are remotely operating my HL-2 for half a year now with a very simple set-up:

@home: I've got my HL-2 connected to a "headless" RaspberryPi:

1a. running piHPSDR as the SDR-program processing the HL-2 output & controlling the HL-2

1b. running VNC-server (installed by default on Raspian Buster) to provide remote acces to the desktop of the headless RPI

1c. running mumble-client to transfer audio between piHPSDR and a (the) mumble-server

1d. running mumble-server to transfer audio between connected clients (typically the mumble-client that's hooked-up to piHPSDR and a remote mumble-client

@remote I "operate" either my MacBook-Air or my Samsung A50 cellphone

2a. running RealVNC to remotely access the headless RaspberryPi located @home
2b. running mumble-client to transfer audio between my MacBook-Air (or my Samsung A50) and the mumble-server @home

Right now I'm on holiday in Bavaria, Germany and attending local 80m net almost daily this way from my camper. It works flawlessly.
By only transferring the audio, made possible by having the headless RaspberryPI @home doing all the signal-processing, the dataflow between my home and my remote device is limited to only 8Kbps?! Implying I can run a one hour net and "consume" less than some 40MB out of my bundle?!

If you like, I can send you a link pointing to a file containing a micro-SD card image I made with all components properly installed.
Flash this image to a microSD-card, put it in your/a RaspberryPI and there you go.

Christiaan,

I would be interested in a copy of your build as well.
