When you add a new 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,” on page 78.
Prerequisites
A routed vApp network.
Procedure
1 Click the My Cloud tab and click vApps in the left pane.
2 Right-click a vApp and select Open.
3 On the Networking tab, select Show networking details.
4 Right-click the vApp network and select Configure Services.
5 Click the NAT tab, select Port Forwarding, and click Add.
6 Configure the port forwarding rule.
a Select an external port.
b Select an internal port.
c Select a protocol for the type of traffic to forward.

Add an IP Translation Rule to a vApp Network
You can configure certain vApp networks to provide IP translation by adding a NAT mapping rule.
When you create an IP translation rule for a network, vCloud Director adds a DNAT and SNAT rule to the
vShield Edge associated with the network's port group. The DNAT rule translates an external IP address to an
internal IP address for inbound traffic. The SNAT rule translates an internal IP address to an external IP address
for outbound traffic. If the network is also using IP masquerade, the SNAT rule takes precedence.
Prerequisites
A routed vApp network.
Procedure
1 Click the My Cloud tab and click vApps in the left pane.
2 Right-click a vApp and select Open.
3 On the Networking tab, select Show networking details.
4 Right-click the vApp network and select Configure Services.
5 Click the NAT tab, select IP Translation, and click Add.
6 Select a VM interface and mapping mode and click OK.
For Manual mapping mode, type an external IP address.
