Gateway Verbindungen für fastd testen

Damit der Router funktioniert, muss er sich per fastd VPN mit den Freifunk Gateways verbinden können. Dazu müssen die Ports 10000-10015 UDP aus dem Netz, in dem der Freifunk Router angeschlossen wird erreichbar sein.

Im UDP Protokoll kann man nicht „pingen“, man kann jedoch versuchen mit nmap zu überprüfen, ob die Ports ereichbar sind, wenn man anstelle des Routers einen Laptop anschließt:

sudo nmap -sUV gw2.ff3l.net -p10000-10015 -v
