Description

Retain UPnP

port forwarding

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.

The following read-only table displays information about the UPnP-created NAT mapping

rule entries in the NAT routing table.

# This is the index number of the UPnP-created NAT mapping rule entry.

Remote Host 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.
