VLAN from one zone connected to an interface from another zone

Hello.


Is it possible to implement such a configuration?

When creating a VLAN, it is possible from the sonicwall interface ... but will it work at all?

Thanks.

    @Dant,

    Welcome to the SonicWall community.

    Yes, the physical interface can belong to a particular zone can have a sub-interface belonging to a different interface. The concept of zones is to make it easier to apply access rules and security policies.

    Please make sure that the access rules are added correctly for that zone that you set up on the VLAN sub-interface. Like Zone_example to WAN allowed etc.,

    Thanks!

    Thanks.


    I hope you fully understood me ... the different interface is to another ZONE.


    All communication is prohibited between the zones.

    Can the communication be set to be based only on a selected VLAN?

    Thanks.


    In fact, I have two zones built quite independently (at the cable level) with each other.

    I want to use the transmission medium, to include a computer that logically belongs to the other zone.

    It is not possible to run a new cable.

  • @Dant,

    Even if traffic is completely prohibited between two zones, specific access rules based on the source/destination IP fields can be added to allow only the necessary traffic.

    I did not follow the cable part, do you have a network diagram or elaborate on the situation at hand?

    Thanks!

    Thanks.

    Something like that ...





  • @Dant,

    Thanks for sharing that. I understand now.

    I hope you know that the VLAN interface under Zone B, can belong to Zone A but needs to have a separate IP scheme. But the access rules can be added such that New PC can communicate to the Zone A PC.

    Thanks!

    Thanks.

    I wanted to make sure it was doable before I started.

    Do only Access Rules need to be changed or NAT?

  • @Dant ,

    In your case, just the access rule should be enough. The SonicWall adds routing policies etc once you configure VLAN sub-interfaces. So, it knows how to forward traffic between those networks.

    If you have any additional queries, please let us know.

    Thanks!
