If you select a NAT-based network connection when you deploy your vCloud Connector Node, you need to set up NAT mapping and firewall rules.

There are multiple approaches to managing this issue. Decide whether you wish to use NAT to forward only the ports necessary for vCloud Connector operation or to forward all ports and then set up a firewall rule to filter all but the following required ports:

Port 443: For communication between vCloud Connector Server and Nodes and between Nodes. This port is used when SSL is enabled; when SSL is disabled, port 80 is used.

Port 5480: For communication with the vCloud Connector Node Admin Web console, for example during the registration process.

Your appliance is deployed and you are logged on to the vCloud Director Web console.


Click the Administration tab and select Networks in the left panel.


Find the network you are using in the Networks list, right-click and select Configure Services.


In the Configure Services dialog box, click the NAT Mapping tab and click Add at the bottom of the tab to create the NAT rule.

The Add NAT Rule popup appears.


Select one of the External IP addresses from the drop-down list.

Note this address if you plan to set up a firewall rule.


If you wish to NAT all ports, enter * for the first port entry.

If you wish to NAT only the required ports, create a rule for each port.


Enter the internal IP address from your initial setup and match the port entry for this rule.


Click OK and click OK again.


If you are using a firewall rule to control traffic, click the Firewall tab and select the Enable firewall check box.


Click Add at the bottom of the pop-up to create a new firewall rule.

Create a rule for each necessary port.

The Add Firewall Rule popup appears.


Give the rule a name and select the Incoming radio button.


Type the source IP address and the source port.

For incoming traffic, the source is the external network. This is the address you selected in Step 4 above.


Type the destination IP address and port.

The destination IP address is the internal IP address from your initial setup.


Select the Allow option.


Select the Enabled option.


Click OK and OK to create the rule.
