Configuring NAT Server

Configuring NAT Server is to map an external IP address and port number to the real IP address and port
number of an internal server on the interface that connects the external network.
An internal server can be located in a common private network or an MPLS L3VPN.
If you specify the acl keyword for the NAT Server configuration, only packets matching the ACL permit
rule are translated. NAT uses only the match criteria of the source IP address, source port number,
destination IP address, destination port number, transport layer protocol, and VPN instance in the ACL
rule for packet matching.

Configuring common NAT Server

Map the real private IP address and port number of an internal server to a public IP address and port
number so that hosts in external networks can access the internal server.
To configure common NAT Server:
Step
1. Enter system
view.
2. Enter interface
view.
