Hi
It will be nice to have toggle "allow connections only to specified ports" on guest network.
It will be useful to allow for example DNS, HTTPS and thats all. I don't want my guests to torrent, SSH somewhere, bruteforce something etc from my connection
I use Flint (1) to share my internet via my neighbors too (guest network) to split internet costs, so there is no guarantee that their guests wont abuse my connection.
