Two VLANs, One DNS, no cross-communication RRS feed

  • Question

  • I'd like to use our domain controller to provide DNS services for a private VLAN we have who's traffic is separated from all other VLANs. The domain controller has a separate NIC that is connected to this VLAN.  What I am not sure on is how to have the domain controller respond to requests on that NIC with the appropriate private IP and at the same time ensure it responds with the correct IP for traffic coming in on the other NIC.

  • Hi Daniel Kaliel,

    1. It's not recommended to make your DC multihomed (owing two NICs), it will cause DNS resolution issues;

    2. Since DNS servers are all not recommended to be multihomed, so it's better to use router devices to build the communication between the VLAN and the DC.

    3. If it's not a huge project to manually add these records, you may set up a standalone DNS server at that VLAN and add related DNS records.

    Best Regards,

    Anne
