Hi there,

I have an ADSL 1mb broadband connection which works fine. I use a Speedtouch 330 ADSL modem and have the free version of Zonealarm installed on my WinXp Home SP2 laptop. The free version of Zonealarm is set to work on Stealth mode.

A test on GRC.com (https://grc.com/x/ne.dll?bh0bkyd2) probing all ports with this setup reports that all ports are "invisible"....i.e. in "stealth" mode.

Now, using GPRS on my mobile-phone, bluetooth and my laptop, a similar test on GRC.com to probe all ports reports that the ports are being detected but are closed. Hmmm...

Yesterday I bought a 3 Com OfficeConnect 11g ADSL Firewall Router. I have set this up and it works fine. I have enabled the inbuilt firewall with protects against 'Ping of Death' and DoS attacks. I have also enable WPA encryption. In addition to this, I also have my Zonealarm firewall.

However, using the wireless setup, a test on grc.com shows that all ports are visible but closed! Argh! :mad: :confused: MOreover, using the same route but having it wired to my laptop using ethernet cable produces the same results!! :confused:

Help! Why is this happening?

I do not understand why it is completely secure when using my wired SPeedtouch modem but not with this new router and when using Bluetooth and GPRS.

:confused: :confused: :confused:

re-ghosted machine to many months ago.... ADSL wired modem works fine and passes all security checks.

tried my cousin's identical wireless router with my laptop and i pass all security checks.

try my own wireless router and don't pass security checks.
