This tool lets you test connection to your Dwarf Fortress Remote server before purchasing the actual DF Remote application.
This is useful if your server is behind a firewall or NAT and youre unsure DF Remote will work. Please note that results may differ when you switch between a cellular and different Wi-Fi networks. You should test the same connection(s) youre intending to use to play.
