You can configure a VMware NSX edge to relay name resolution requests from clients to external DNS servers. Once configured VMware NSX Edge Services Gateway (ESG)  will forward name resolution request from clients to an external DNS Server. An ESG will relay client application requests to the DNS servers to fully resolve a network name and cache the response from the servers

In this blog, I will show you how to configure the DNS servers on the NSX edge.

Log in to the vSphere Web Client. Click Networking & Security 

Click NSX EdgesDouble-click on NSX Edge.

Click on Configuration –> DNS Configuration

Click Enable DNS Service to enable the DNS service. Type the IP Address of External DNS Server. Configure “Cache Size” and “Enable Logging” in case required

Post configuration NSX edge will relay the name resolution requests for any VM’s traffic that flow through it, to the configured external DNS servers.


This concludes the configuration of an external DNS server on Vmware NSX Edge Gateway Servies Router. Hope this will be informative for you. Please share if you find worth sharing it. Thanks for Reading!!!.
