Have you ever wondered whether your firewall is actually working properly. Well there is only one way to find out, and that is to test it. Remember you shouldn’t find any open ports. If you do, then you should lock the ports down. Some firewalls will block port scanning. If your firewall does, then you will need to disable it and then re-enable it when the scanning is complete. Here are some of the firewall testing services I suggest you use (you could use all three):

Comment: Easy to use but doesn’t provide browser header and message spam scanning
Note: Some Internet Security products list the links on this site as malicious. You can feel safe in the knowledge the links are actually safe.

Comment: Comprehensive but not the easiest to use for the novice – RECOMMENDED by me if you want to fully test your firewall.
Audit My PC
Comment: Simple to use and comprehensive. Best all of it sends you a scan report by email.
Safe surfing folks!
