Nav passed except for the privacy test.

Opera passed all with flying colors, including all the exploits test.
I was using Tiny. Didn't want to try with Sygate as I haven't had time to configure it properly yet.

Thanks for the links, Blacksheep.

*] Tested TooLeaky and Firehole on MSIE 5.0*, Sygate PF Free:

TooLeaky made not a dent- no packets in or out.

Firehole bored right thru- Here's CommView sniffer reconstructed TCP session (with xs strategically placed to cover my private parts):

Message from user "current user" on computer C*F4Z2 [xxx.xxx.86.*60] at *2/28/0* *7:02:*4
***** I have successfully bypassed the personal firewall! *****

HTTP/*.* 400 Bad Request
Date: Fri, 28 Dec 200* 2*:02:*4 GMT
Server: Apache/*.*.*4
Connection: close
Content-Type: text/html; charset=iso-885*-*

<H*>Bad Request</H*>

2] Tested TooLeaky and Firehole on MSIE 5.5, Sygate PF Pro 5.0 beta with all Options> Security tab> checkboxes checked:

Tooleaky reports "Success!" True. CommView sniffer and SPF Pro recorded packet traffic between my PC and Tooleaky target grc 207.7*.*2.*** so firewall breached.

Firehole reports "failed to connect Failed to send message" True. SPF Pro popped a flag on IE saying a dll might have been loaded, will I allow connect. I said no. No packet traffic.

Firehole breached SPF Free but not SPF Pro 5.0 beta.
Tooleaky breached SPF Pro 5.0 beta but not SPF Free.

IMHO one must use sniffer to know for sure when running these tests. All of these firewall leak tests require code running in one's PC. If rogue code gains entry to one's PC one is probably dead meat anyway if programmer is good.

What to do? Don't get any trojans and hope firewall vendors plug the holes.

Sleep tight.

Please note that there are 4 pages.

(After reading this, I suppose that LooknSee is the FW of choice...?)

Disturbing! Ignorance is bliss.

Look 'n' Stop http://www.looknstop.com/En/index2.htm is now at the top of my agenda of firewalls to test. Have hopes Sygate will get their act together for SPF to block all firewall leaks including nonstandard packets.

Thanks for post Nulland Void.

Yeah right, LooknStop. (no wonder I had such a hard time finding it at Google!)

My computer is becoming very depressed and threatens to commit suicide unless I go back to Linux.
