    It might be best to read the manual that came with the router and or help files. My linksys wireless does tell how to configure the router maybe yours will also. ;)

    Hi stevlo

    Using a port scanner on your own system to scan it is different than having a remote system scan you. Scanning your own system is done locally and will not reflect any firewalls/routers in place. The same results could be obtained using netstat or a port mapper.

    If you want to test how your configuration appears to the outside you have to be scanned by a remote system. In this post, Tassie's Tests/Tutorials/Topics/Tips Sites, you will find a list of sites you can go to have your system scanned.

    A port mapper would help you see and understand what is going on with those open ports:
    Port Explorer
    Vision
    Active Ports

    Regards,
