Add a Firewall Rule to a vApp Network
You can add firewall rules to a vApp network that supports a firewall. You can create rules to allow or deny
traffic that matches the rules to pass through the firewall.
In order for a firewall rule to be enforced, you must enable the firewall for the vApp network. See “Enable the
Firewall for a vApp Network,” on page 70.
When you add a new firewall rule to a vApp network, it appears at the bottom of the firewall rule list. See
“Reorder Firewall Rules for a vApp Network,” on page 72 for information about setting the order in which
firewall rules are enforced.
If a system administrator specified syslog server settings and those settings have been applied to the vApp
network, then you can log firewall rule events. For information about applying syslog server settings, see
“Apply Syslog Server Settings to a vApp Network,” on page 78. To view the current syslog server settings
see “View Syslog Server Settings for a vApp Network,” on page 77.
