Figure 27 Basic configuration wizard: 5/6 (NAT configuration)

Table 11 NAT configuration items

Item Description

Interface

Select an interface on which the NAT configuration will be applied. Generally, it is

the outgoing interface of the device.

Dynamic NAT

Specify whether to enable dynamic NAT on the interface.

If dynamic NAT is enabled, the IP address of the interface will be used as the IP

address of a matched packet after the translation.

By default, dynamic NAT is disabled.

Source IP/Wildcard If dynamic NAT is enabled, set the source IP address and wildcard for packets.

Destination

IP/Wildcard

If dynamic NAT is enabled, set the destination IP address and wildcard for packets.

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).

Internal Server

Specify whether to enable the internal server.

You can configure an internal server on the NAT device by mapping a public IP

address and port number to the private IP address and port number of the internal

server.

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 the internal server is enabled, set the valid IP address and service port number

for the external access.
