Configuring Edge Gateway Services
You can configure services, such as DHCP, firewalls, network address translation (NAT), and VPN for edge
gateways. Organization administrators can also configure some network services for their edge gateways.
Configure DHCP for an Edge Gateway
You can configure edge gateways to provide DHCP services to virtual machines connected to associated
organization virtual datacenter networks.
Prerequisites
System administrators and organization administrators can configure DHCP.
Procedure
1 Click the Manage & Monitor tab and click Organization VDCs in the left pane.
2 Double-click the organization virtual datacenter name to open the organization virtual datacenter.
3 Click the Edge Gateways tab, right-click the edge gateway name and select Edge Gateway Services.

vCloud Director updates the edge gateway to provide DHCP services.
NOTE If the DNS settings on a DHCP-enabled edge gateway are changed, the edge gateway no longer
provides DHCP services. To correct this issue, disable and reenable DHCP on the edge gateway.

datacenter that are being sent to another organization virtual datacenter network or an external network.
