Prerequisites
A routed vApp network or an isolated vApp network.
Procedure
1 Click the My Cloud tab and click vApps in the left pane.
2 Right-click a vApp and select Open.
3 On the Networking tab, select Show networking details.
4 Right-click the vApp network and select Configure Services.
5 Click the DHCP tab and select Enable DHCP.
6 Type a range of IP addresses or use the default range.
vCloud Director uses these addresses to satisfy DHCP requests. The range of DHCP IP addresses
cannot overlap with the static IP pool for the vApp network.
7 Set the default lease time and maximum lease time or use the default values and click OK.
8 Click Apply.
vCloud Director updates the network to provide DHCP services.
NOTE If the DNS settings on a DHCP-enabled vApp network are changed, the vApp network no longer
provides DHCP services. To correct this issue, disable and reenable DHCP on the vApp network.
Configure the Firewall for a vApp Network
You can configure certain vApp networks to provide firewall services. Enable the firewall on a vApp
network to enforce firewall rules on incoming traffic, outgoing traffic, or both.
When you enable the firewall, you can specify a default firewall action to deny all incoming and outgoing
traffic or to allow all incoming and outgoing traffic. You can also add specific firewall rules to allow or deny
traffic that matches the rules to pass through the firewall. These rules take precedence over the default
firewall action. See “Add a Firewall Rule to a vApp Network,” on page 75.
If a system administrator specified syslog server settings and those settings have been applied to the vApp
network, then you can log events related to the default firewall action. For information about applying
syslog server settings, see “Apply Syslog Server Settings to a vApp Network,” on page 82. To view the
current syslog server settings see “View Syslog Server Settings for a vApp Network,” on page 82.
