Description
Select this check box to have the Business Secure Router retain UPnP
created NAT rules even after restarting. If you use UPnP and you set a
port on your computer to be fixed for a specific service (for example,
FTP for file transfers), the Business Secure Router can keep a record
when your computer uses UPnP to create a NAT forwarding rule for that
service.
This is the index number of the UPnP-created NAT mapping rule entry.
This field displays the source IP address (on the WAN) of inbound IP
packets. Because this is often a wildcard, the field can be blank. When
the field is blank, the Business Secure Router forwards all traffic sent to
the External Port on the WAN interface to the Internal Client on the
Internal Port. When this field displays an external IP address, the NAT
rule has the Business Secure Router forward inbound packets to the
Internal Client from that IP address only.
