    @J_de_Haan_2020 model 7590 is for Cabel Internet. You have no connection Port on the Firewall for cable.

    So this is the best way to use full sonicwall security services by redirecting to with exposed host function.

    Keep in mind that WLAN on the Fritzbox then is outside the LAN Zone. And don´t plug in other LAN connection in the Fritzbox directly.

    And have a look for managment of the Fritzbox from WAN side. Maybe you need this Port on the Firewall´s WAN Port too.

    Hi @J_DE_HAAN_2020,

    Thank you for visiting SonicWall Community. 

    Are you planning to use TZ 400 as a router or insert TZ 400 into the existing network without changing the network setup but still make use of the TZ 400 as a firewall applying security policies and terms? Please explain and we can provide appropriate suggestions.
