How to: configure the Firewall for an Organization vDC Network

As an organization administrator will be responsible for configuring your organization vDC networks and sometimes this will require setting configuring firewall services. Enable the firewall on an organization vDC 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.

If you have specified syslog server settings and applied them to the organization vDC network, then you will be able to log events related to the default firewall action.
