You can configure certain vApp networks to provide port forwarding by adding a NAT mapping rule. Port forwarding provides external access to services running on virtual machines on the vApp network.

When you configure port forwarding, vCloud Director maps an external port to a service that runs on a virtual machine dedicated to inbound traffic.

When you add a port forwarding rule to a vApp network, it appears at the bottom of the NAT mapping rule list. For information about how to set the order in which port forwarding rules are enforced, see Reorder Port Forwarding Rules for a vApp Network.
