Wireshark · Ethereal-users: Re: [Ethereal-users] Ethereal & ZoneAlarm Pro Firewall Interfere!

The difference could be a software version.

The latest ZoneAlarm (v 5?) was showing different network behaviour
(on a low network level) from earlier versions.

This is just a thought. It may or may not be directly related to what
was experienced.
