Hotspot users on ver rc_5 - Use of Zone Alarm etc on clients

Hi

I have successfully been using ver rc_5 on our ethernet based hotspot system. It seems pretty stable.

We have found one major difference from ver 2.8, however, and this is that clients (typically running Win XP) have to disable their Zone ALarm firewalls to be able to use the system. They were able to use them when we were running ver 2.8.

Anyone know why this might be ??

thanks and rgds

What does that ZoneAlarm firewall say about the hotspot system? maybe inspect logs or something, so that we would know what actions exactly trigger the alarm.
