Windows Vista Firewall

If I didn’t know, I would say it sucks and install another firewall, like ZoneAlarm for all my other XP computers. However, after an issue with delay and slow connection to localhost, I have identified the problem is with conflicting firewalls. Uninstalled ZoneAlarm, then tweak Vista Firewall, it’s quite powerful (use w/ Advanced Security option). You’ll be able to add/edit rules just like iptables under Linux. For my purpose, I created a trusted zone for local IP addresses (192.168.2.0/24) and things flies again. Don’t use the default settings, but you don’t have to do much. Just block all incoming AND outgoing for all level (Domain, Public, Private) and check those Enable rules. Only let things out/in under your control.
