Remember, if you are running 2 similar programs … XP’s firewall & ZoneAlarm … at the same time that there may be some interference between the 2 programs. This could have allowed your problem. :frowning:

If it were me, I would turn off the XP firewall as it only provides inbound protection and I suspect that it does not close all ports. :-\

ZoneAlarm is so much better! :slight_smile:
