ugh...this is way more impact...a 128k ISDN customer running an NT/Win2k

processor load is WAY up just from the requests, and the logs are growing
like mad.

I'm sitting behind a dialup box right now, and I just added a log
clause to an ipf rule matching connection attempts to port 80.

I'm averaging 35 probes per minute. Blocking them is quite beneficial
to performance on a v.34 connection :)
