Thanks.
.... sheldsup at GRC.com seems to be gone!?!
And yes, I would like to test my two PCs from outside...see, if everything is OK.
It looks you are an expert ... I can not perform those tests you are explaining.
I have a D-Link DI-524 AirPlus G High Speed 2.4GHz Wireless Router, 802.11b, g .... and it looks like the firewall is off, but I am reluctant to put it on .... had lots of problems with McAffee firewall some time ago.
I also run Zone Alarm, Windows Defender, AVG, Ewido, Spybot and Ad-Aware....
