[plug] firewall computer - was Re: [plug] Has anyone else seen a flurry of Windows probes recently?

[William Kenworthy]

On a reasonably fast machine, doing only firewall duties I do not think
it would have much of an effect.  I did dome c programming on serial
ports on a 16Mhz 386 under dos some (many) years ago and it only had a
effect when trying to run windoze (3.0!)  Mind you the modem was only a
14.4 ...
