Configure IP Address Persistence
By default, when you stop a running vApp or power off a virtual machine, vCloud Director releases any IP
and MAC addresses the virtual machines were using. You can configure a vApp to retain the network
addresses of its virtual machines until the vApp, VM, or network is deleted.
Static routing relies on the IP addresses of the virtual machines and virtual routers in a vApp. For vApps
that use static routing, enable IP persistence to make sure that static routes to and from the vApp remain
valid.
Procedure
1 Click My Cloud.
2 In the left pane, select vApps.
3 Select a vApp, right-click, and select Open.
4 On the Networking tab, select the Always use assigned IP addresses... check box and click Apply.
The virtual machines in the vApp keep their assigned IP and MAC addresses, even when they are powered
off.
View Syslog Server Settings for a vApp Network
You can view the syslog server settings for a routed vApp network.
vCloud Director supports logging events related to firewall rules to a syslog server specified by a system
administrator.
If a vApp network does not have any syslog server settings and you think it should, or if the settings are not
what you expected, then you can synchronize the network with the most current syslog server settings. See
“Apply Syslog Server Settings to a vApp Network,” on page 82. If there is still a problem after you
synchronize, contact your system administrator.
Prerequisites
A routed vApp network.
Procedure
1 Click My Cloud.
2 In the left pane, click vApps.
3 Select a vApp, right-click, and select Open.
4 On the Networking tab, select a vApp network, right-click, and select Properties.
5 Click the Syslog Server Settings tab.
Apply Syslog Server Settings to a vApp Network
You apply syslog server settings to a routed vApp network to enable firewall rule logging.
Syslog server settings can only be specified by a system administrator. You should apply those settings to
any vApp network that was created before the system administrator specified them. You should also apply
the syslog server settings to a vApp network any time a system administrator changes the settings.
Prerequisites
A routed vApp network.
