Mikrotik (Client) L2TP VPN mit Sophos XGS 2100

Denis Denk1

Hallo Zusammen,

ich habe ein neues Sophos XGS 2100, aktuell ohne Lizenz. Wir sollen von UTM auf XGS migrieren.

Für Homeoffice benutzen wir Mikrotik als L2TP/IPsec (client). Alles supe läuft mit UTM SG320, aber funktioniert mit XGS 2100 nicht.

Planen:

Mikrotik -- (LAN) --> Home Router -- (WAN) --> Sophos UTM / XGS.

Die Konfiguration für L2TP habe ich mit Windows geprüft, die Verbindungen wurde hergestellt.  Sophos XGS zeigt in der Protokolldatei darüber an.

Wenn ich mit Mikrotik versuche, dann zeigt Sophos XGS in der Protokolldatei darüber nichts an.

In Packet capture:

Mikrotik zeigt, dass erste Phase terminated.

Wer hat Erfahrungen bitte HELP! :))

    Hello Denis,

    Thanks for reaching out to Sophos Community and hoe you are well. 

    Kindly try creating a FW rule for VPN to allow traffic:  https://support.sophos.com/support/s/article/KB-000035835?language=en_US

    Based on the reason of Violation on the packet capture it seems there are no Local_ACL (Firewall rule) to allow the traffic to pass through.

    Hope this helps. Thank you for your time and patience and thank you for choosing Sophos.

    Cheers,

    Wenn die "local ACL" die Zugriffe verhindert, horcht entweder die XG nicht auf diesem Interface ... oder es fehlt eine NetWork-Protection-Lizenz (oder wnigstens die Trial-Lizenz).

    ... würde ich sagen

    Hallo,

    richtige Lizenz haben wir.
    Ich habe extra L2TP-Client auf Windows eingerichtet, das geht ohne Probleme.
    Ich vermute etwas mit zwei NAT nicht richtig funktioniert.

    Hallo zusammen,

    endlich habe ich das Problem gelöst!
    Nach diese Einstellungen, was ich davor geschrieben habe, habe ich Mikrotik bis die Version 7.8 Stable upgedatet. 

    Und es hat auf Anhieb geklappt!
