Is there a way I can share the local IP webpage to the public on my website or is this a no, no?
You can use port forwarding in your router to do that. Basically you have it map from the WAN IP (Outside) to the LAN IP (Internal) that the FlightFeeder is using on port 8080.
You’d want to put the FlightFeeder on a static LAN IP and if your ISP uses dynamic IP then you can use a DDNS service like dnsdynamic.
It can be dangerous to do this, anyone connecting will have the same privileges as you do internally if any.
