All configurations you have made in the basic configuration wizard are displayed.
Description
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.
Specify the source IP address and wildcard for matching packets.
These fields are available only when dynamic NAT is enabled.
Specify the destination IP address and wildcard for matching packets.
These fields are available only when dynamic NAT is enabled.
Specify the protocol type for matching packets. Valid values include TCP, UDP, and
IP (IP indicates any protocol carried by the IP protocol).
This field is available only when dynamic NAT is enabled.
Specify whether to enable the internal server.
If the internal server is enabled, when an external user accesses the internal server,
the NAT function translates the destination address of the request packets into the
private IP address of the internal server. Accordingly, when the internal server
replies, the NAT function translates the source address (private IP address) of reply
packets into the public IP address.
By default, the internal server is disabled.
IMPORTANT:
Configuring the internal server might break your connection to the UTM device. For
example, if you specify the IP address of your local host or the IP address of your access
interface as the external IP address, your connection will be broken.
Specify the IP address and service port number for external user access.
These fields are available only when the internal server is enabled.
Configure the IP address and service port number of the internal server.
These fields are available only when the internal server is enabled.
