Ich habe auf dem Client zum Test mal eine etwas größere Datei heruntergeladen und siehe da: Der Traffic erhöht sich in der Folge tatsächlich bei beiden VPN-Verbindungen. Somit scheinen beide Tunnel wohl kaskadiert zu laufen.
Mein aktuelles Setup funktioniert allerdings anscheinend nur solange, bis es zur nächtlichen Zwangstrennung kommt. Anschließend werden beide VPN-Tunnel zwar wieder verbunden, aber der Client hat trotzdem keinen Internetzugang.
Erst wenn ich beim VPN-Client PIA_SCHWEIZ das Interface einmal manuell von PIA_LUXEMBURG auf WAN und wieder zurück auf PIA_LUXEMBURG stelle, hat der Client im LAN wieder Zugang zum Internet.
Hat jemand eine Idee woran dies liegen könnte?
