Test Your Firewall

My results ...

Your Internet port 139 does not appear to exist!

One or more ports on this system are operating in FULL STEALTH MODE! Standard Internet behavior requires port connection attempts to be answered with a success or refusal response. Therefore, only an attempt to connect to a nonexistent computer results in no response of either kind. But YOUR computer has DELIBERATELY CHOSEN NOT TO RESPOND (that's very cool!) which represents advanced computer and port stealthing capabilities. A machine configured in this fashion is well hardened to Internet NetBIOS attack and intrusion.

Unable to connect with NetBIOS to your computer.

All attempts to get any information from your computer have FAILED. (This is very uncommon for a Windows networking-based PC.) Relative to vulnerabilities from Windows networking, this computer appears to be VERY SECURE since it is NOT exposing ANY of its internal NetBIOS networking protocol over the Internet.

Can you pass this test?

:rolleyes: I'm secured with my router's firewall and I have two recognized ports open! :)

Attempting connection to your computer. . .

Shields UP! is now attempting to contact the Hidden Internet Server within your PC. It is likely that no one has told you that your own personal computer may now be functioning as an Internet Server with neither your knowledge nor your permission. And that it may be serving up all or many of your personal files for reading, writing, modification and even deletion by anyone, anywhere, on the Internet!

Preliminary Internet connection refused!

This is extremely favorable for your system's overall Windows File and Printer Sharing security. Most Windows systems, with the Network Neighborhood installed, hold the NetBIOS port 139 wide open to solicit connections from all passing traffic. Either this system has closed this usually-open port, or some equipment or software such as a "firewall" is preventing external connection and has firmly closed the dangerous port 139 to all passersby. (Congratulations!)

I passed all tests includig port probe, all my ports are in stealth mode, all incoming NETBIOS blocked, and so on :)

I'm using ZoneAlarm Pro 3.7.159, but i think that I'll buy version 4 : it's a very efficient firewall for me and one of the bests in the world :rolleyes: Thanx a lot for the URL MSFN, as always you're on top :D
