Enable IP Masquerading for an Organization Network
An organization administrator can configure certain organization networks to provide IP masquerade services.
Enable IP masquerading on an organization network to hide the internal IP addresses of virtual machines from
the external network.
When you enable IP masquerade, vCloud Director translates a virtual machine's private, internal IP address
into a public IP address for outbound traffic.
Prerequisites
A routed organization network.
Procedure
1 Click Administration.
2 Select Cloud Resources > Networks.
3 Right-click the organization network name and select Configure Services.
4 Click the NAT Mapping tab and select Enable IP Masquerade.
5 Click OK.
Add a Port Forwarding Rule to an Organization Network
An organization administrator can configure certain organization networks to provide port forwarding by
adding a NAT mapping rule. Port forwarding provides external access to services running on virtual machines
on the organization network.
When you configure port forwarding, vCloud Director maps an external IP address and a port to a service
running on a port on a virtual machine for inbound traffic.
When you add a new port forwarding rule to an organization network, it appears at the bottom of the NAT
mapping rule list. For information about how to set the order in which NAT mapping rules are enforced, see
“Reorder NAT Mapping Rules for an Organization Network,” on page 27.
Only system administrators can assign external IP addresses to a network. Contact your system administrator
if your organization network lacks external IP addresses.
