    I have a home network setup with several workstations and servers. I am using a BEFSR11 Router. I noticed something rather strange the other day in WallWatcher that has me kind of worried. I know just enough about networking to be considered dangerous. To set the stage one of my servers is IP and that is the box that has the DNS Server installed using W2K Server. I have the Router UPnP setup to forward Port 53/UDP requests to this IP. My personal workstation is IP running WinXP SP1A. WallWatcher is reporting that Port 53 requests are going to both and How can this be when the BEFSR11 is forwarded to Last night I upgraded the Firmware and this didn't make a difference. I have been told I need to run a packet sniffer and others have said to turn on the firewall in WinXP on that workstation. All sound like good options but I am still trying to understand how the Router can be configured to do one thing and it does that and also something else?

    The purpose of UPnP is to dynamically open works as and when they are needed, this works alongside the normal port forwarding and triggered port forwarding options. Most feel that UPnP is a big security risk and advise switching it off. That's not to say that it is the cause of your problem, but if you don't specifically need it then it's best to disable it.
