Configure DNS on VMware NSX Edge


A NSX edge can be used to relay name resolution requests from clients to external DNS servers. As the NSX relay these requests, it caches the response from the DNS server. In this blog post, I will show you how to configure the DNS servers on the NSX edge.

First, navigate the Networking & Security.


Click NSX Edges and double click your edge device that will be relaying the DNS requests. In my case, it is my Perimeter Edge device.


Under Manage > Settings > Configuration, click Change on the DNS Configuration box.


Enter the IP address of the external DNS server(s). Click OK.


If you refresh the services status menu, you should see the DNS service is Up.


Now the NSX edge will relay the DNS requests for any VM’s traffic that flow through it, to the external DNS servers.
