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 edge gateway 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.


Verify that you have a routed vApp network.
