Protocol Type

If dynamic NAT is enabled, select the protocol type carried over the IP protocol,

including TCP, UDP, and IP (indicating all protocols carried by the IP protocol).

 

 

 

 

Specify whether to enable the internal server.

 

If the internal server is enabled, when a user from the external network accesses the

 

internal server, the NAT translates the destination address of request packets into the

 

private IP address of the internal server. When the internal server replies to the

 

packets, the NAT translates the source address (private IP address) of reply packets

Internal Server

into a public IP address.

By default, the internal server is disabled.

 

 

IMPORTANT:

 

Configuration of the internal server may result in disconnection with the device (for

 

example, specify an external IP address as the IP address of the local host or as the IP

 

address of the current access interface). Perform the operation with caution.

External IP: Port

When you enable the internal server, set the valid IP address and service port number

for the external access.

 

 

 

Internal IP: Port

If you enable the internal server, set the IP address and service port number for the

server on the internal LAN.
