    Nur das TUHH Netzwerk durch dass VPN routen
    Sie überschreiben hiermit lokal auf eigene Verantwortung die Routen / Strecken, sodass Sie beispielsweise für Verlage nicht aus der TUHH kommen und in offenen WLAN Netzwerken keine vollständige Verschlüsselung genießen.
    Bearbeiten Sie die TUHH VPN Einstellungen und öffnen Sie den Reiter IPv4. Die Option Diese Verbindung nur für Ressourcen in deren Netzwerk verwenden verhindert das Setzen der Routing Regel mit der alle Pakete durch das VPN getunnelt werden. Die eigene Route / Strecke definiert dafür manuell das TUHH Netzwerk:
    • Adresse:
    • Netzmaske:
    • Gateway:
    • Metrik: 5
    Die Routen sollten bei einer neuen Verbindung wie folgt aussehen:
    $ route -n
    Ziel            Router          Genmask         Flags Metric Ref    Use Iface         U     50     0        0 vpn0     U     5      0        0 vpn0
    134.28.140.xxx UH    50     0        0 vpn0
