      Sorry if this has been answered already.  I have not been able to find the info I need.  Is there a way to limit UPNP to just one client PC on my network?  I wanted to just open it up to one machine just for gaming purposes.

      Thank you.

        You mean like the UPnP Access Control Lists GUI?

          I am pretty new to this but that sounds just like what I need.  Any help with configuration is highly appreciated.

            It's pretty self-explanatory.  Check the Enable box.  Fill in at least one ACL as per the format shown:

            Format: [allow or deny] [ext port or range] [int ipaddr or ipaddr/CIDR] [int port or range]
            Example: allow 1024-65535 192.168.0.0/24 1024-65535

            The example allows all ports between 1024 and 65535 internal/external to be opened by all users on the 192.168.0.0 subnet.  Perhaps if you explain exactly what you're trying to do, we can help with that.

              Thank you for the help.  I think I have it setup. I am trying to make it easier to play games on a single PC on my network.  Here is what I have entered  allow 88-65535 192.168.1.4/24 88-65535.

                I am still getting UPNP mappings for other machines on my network.  I am trying to limit UPNP to a single machine on my network.

                  You have to use a /32 on the CIDR mask to limit the match to a single address. Like so:

                  
                   allow 1024-65535 192.168.0.101/32 1024-65535
                  
                  

                  192.168.1.4/24 is the same as 192.168.1.0/24 for all intents and purposes.
