Configuring an internal server
Introduction to internal server
To configure an internal server, you need to map an external IP address and port number to the internal
server. This is done through executing the nat server command on an interface.
Internal server configurations include external network information (external IP address global-address
and external port number global-port), internal network information (internal IP address local-address
and internal port number local-port), and internal server protocol type. According to different
internal/external network information configurations, internal servers can be classified into common
internal servers and load sharing internal servers.
Both internal servers and their public IP addresses can support MPLS VPN. If an internal server belongs
to an MPLS VPN instance, you also need to specify the vpn-instance-name argument. With this argument
not provided, the internal server is considered belonging to a normal private network.
NOTE:
The LB module does not support load sharing internal servers.
Configuring a common internal server
After mapping the private IP address/port number (local-address and local-port) of a common internal
server to a public IP address/port number (global-address and global-port), hosts in external networks
can access the server located in the private network.
Follow these steps to configure a common internal server:

NOTE:
• The LB module supports using the interface address as the public address of an internal server, which is
the Easy IP feature. If you want to specify an interface, the interface must be a loopback interface and
must already exist.
