    Nope, never had a problem.  Perhaps a vulnerability or flaw in the modem
    itself?
    
    Of course, the upload speed is slow but you know that since you work for
    Covad.
    
    I ran ISS IS through mine.

    Subject: DSL modems used for pen-testing
    
    Has anyone else run into the problem of "swamping" the connection tables 
    in their DSL modems (on the attack side and the target side)? I 
    currently have a Zyxel 643 router/ADSL modem that I "wanted to use for 
    pen-testing, but the darn thing dies when doing something as simple as a 
    port scan.
    
    I you have run into the problem, what was the fix other than throttling 
    the scanning app? If a new modem, which one?
    
    TIA
    
    Toby
