I am using an AirPort Extreme to connect my PS3 to a Comcast cable modem.  After having connection problems, I was advised by Sony support to place the PS3 in the DMZ.  I understand that a node can be placed in the DMZ by setting its private IP address in the “Default Host” field under the NAT tab.  Do I also need to check the “Enable NAT Port-Mapping” box?

    No, as this second option would require the NAT firewall. With the PS3 as the default host, all NAT ports would be open.

    Thanks for the response.  If NAT-PMP is enabled, does it apply to all nodes behind the NAT?  If a node is compatible with NAT-PMP, does that eliminate the need to manually configure port-mappings for that node?

     

    Thanks again.

    Yes.

    If an application is NAT-PMP compatible, that is true. It is similar to UPnP.
