Table 11 Configuration items
Item Description
Interface Select an interface on which the NAT configuration will be applied.
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.
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
into a public IP address.
By default, the internal server is disabled.
IMPORTANT:
Configuration of the internal server may result in disconnection with the firewall (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.
Internal IP: Port
If the internal server is enabled, set the IP address and service port number for the
server on the internal LAN.
