Specify the addresses of your private DNS servers so that the management gateway, ESXi hosts, and management VMs resolve fully-qualified domain names (FQDNs) to IP addresses on the management network.

To use features such as migration with vMotion, cold migration, or Hybrid Linked Mode, switch the vCenter Server resolution to a private IP address resolvable from the VPN.


Use the Configure MGW VPN wizard to create the management network, gateways, and firewall rules.


  1. Specify the DNS server addresses.
    Click Edit and enter the IP addresses for DNS Server 1 and, optionally, DNS Server 2.
  2. Choose a scope for DNS name resolution.
    By default, the management gateway DNS is configured to resolve names to addresses on the public Internet ( Public IP resolvable from Internet). To limit the scope to addresses on the management VPN. Select Private IP resolvable from VPN. This configuration change applies to both DNS Server 1 and DNS Server 2.
  3. Click NEXT STEP to save the management gateway DNS configuration and test management network connectivity.
