| Ingress interface |
Select ANY or any L3 interface from the drop-down list to
act as the interface for network traffic that originates from outside of the network’s
routers and proceeds toward a destination inside of the network.

| Destination IP translation |
Select from the following options:
- Use Ingress Interface IP—Ingress Interface IP address
range specified will be used for translation. When not using the ingress interface
IP address, users must explicitly specify an interface with the next option, Use
Virtual IP address.
- Use a Virtual IP address—When users specify an external
IP address range, the translated IP address range is generated automatically
according to the beginning of the IP address. The mapping is one-to-one
mapping.
- Port Forward—Check the Port Forward check box for static
one-to-one NAT mapping with port forwarding: an external IP address is always
translated to the same mapped IP address, and an external port number is always
translated to the same mapped port number. Select the protocol from Any, TCP, or
UDP. (Any means all protocols.) When users specify the External Service Port
range, the Map to Port will be generated automatically according to the beginning
port. The mapping is one-to-one mapping.
