Virtual Private Cloud OnDemand Networking Guide

See Configure DHCP for an Edge Gateway in vCloud Director Administrator’s Guide for more information.
NOTE Before you enable DHCP for a routed network and add an IP address pool, you must determine a
valid range for the IP addresses assigned by DHCP.
You can view the public IP addresses you have allocated to a gateway by clicking the Gateways tab from
the Virtual Private Cloud OnDemand Web UI, clicking the gateway for which to view public IP addresses,
and clicking the Public IPs tab. The list of Public IP addresses allocated to that gateway appears.
Isolated Network
DHCP is disabled by default for isolated networks.
Configure DHCP for an isolated network by navigating from Virtual Private Cloud OnDemand to the Org
VDC Networks tab for the virtual data center in vCloud Director:
Virtual Private Cloud OnDemand Web UI > Networks tab > Manage in vCloud Director > vCloud Director
Administration page > Org VDC Networks tab > select the isolated network, right-click and choose
Configure Services > DHCP tab
Load Balancer
Gateways in Virtual Private Cloud OnDemand support load balancing for the virtual machines connected to
routed networks.
In Virtual Private Cloud OnDemand, a load balancer for a gateway has a virtual server and corresponding
server pool. The virtual server and server pool have the following characteristics:
n
The virtual server has a public IP address and services all incoming client requests.
n
The server pool assigned to the virtual server is responsible for all load balancing.
Because a gateway supports up to nine interfaces, the load balancer service supports multiple server pools
and separate load balancing methods for each server pool (as shown in the following graphic).

Pool servers
See Add a Pool Server to an Edge Gateway in vCloud Director Administrator’s Guide for a description of each
load balancing method.
To configure load balancing for a gateway, do the following tasks:
1 Determine which public IP address is allocated to the gateway before you configure load balancing for
it by clicking the Gateway tab from the Virtual Private Cloud OnDemand Web UI > gateway name >
Public IPs tab. The list of public IP addresses allocated to the gateway appears.
