If I enable "activate wlan security (nft filter)", I can connect via wifi to my RPi and see the SignalK server on port 3000. With the option disabled, the wifi connection succeeds but the server isn't accessible. Will the documents explain what the option does?
The good news is that with the option enabled, I can now share internet via USB tethering. Great work!
Are you sure about that behavior? you will only notice the effect of "activate wlan security (nft filter)" in this scenario:
- OpenPlotter set as an AP using the built-in wifi.
- OpenPlotter set as a client using a wifi dongle connected to the marina AP.
- Any device onboard connected to the Raspberry AP can connect to the signal k server and have access to internet using the shared connection of the marina.
On that scenario if "activate wlan security (nft filter)" is not enabled, any boat connected to the marina AP could access to your signal K server and other services of your OpenPlotter or even any device onboard. Usually routers in marinas are protected against this but you never know.
If you are using your phone in the same scenario instead of the marina wifi, you probably will be protected because mobile internet providers are always protected, or maybe not, you know the big brother is always there...
Actually you do not need to set an AP to enable "activate wlan security (nft filter)". You will be also protected if you just connect to the marina as a client.
This will be in docs of course.
