The gateway provides a Domain Name System (DNS) server to networks within Virtual Private Cloud OnDemand. You can choose to use the DNS services provided by the gateway or you can specify an alternative DNS server. If you choose to use the gateway DNS service, DNS relay must be preconfigured on the gateway.

You can configure external DNS servers to which the gateway can relay name resolution requests from clients. When an external DNS server is configured, the gateway relays client application requests to the DNS servers to fully resolve a network name and cache the response from the servers.

To configure DNS for your virtual machines in Virtual Private Cloud OnDemand, update the default DNS settings in vCloud Director. Access the DNS settings in vCloud Director by navigating from Virtual Private Cloud OnDemand to the following area of vCloud Director:

Virtual Private Cloud OnDemand Web UI > Networks tab > Manage in vCloud Director > vCloud Director Administration tab > Org VDC Networks tab > select the network, right-click and choose Properties > Network Specification tab

See Modify an Organization Virtual Datacenter Network DNS Settings in vCloud Director Administrator’s Guide for information.


If the DNS settings on a DHCP-enabled gateway are changed, the gateway no longer provides DHCP services. To correct this issue, disable and re-enable DHCP on the gateway. For information about enabling DHCP, see the following documentation:
