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
