    Nope you are allowing traffic on 80 i would guess which is what leaktest uses and you would not really want to block this :)

    LeakTest is made for testing software firewalls not hardware devices.

    Your fine :)

    Do you use a software firewall to?

    "Penetrated" is a bit vague to say the least. I hope LeakTest provided some more details?

    Its very concervative with helpful info but is old and quite useless now anyway.

    It refers you to http://grc.com/lt/leaktest.htm

    Its only a basic test, something like Robin Keirs firehole is nice s it uses DLL injection to show you even your software firewall is pants, coupled with NetCat is nice as you can change the port away from 80 and for incorrectly configured rule based firewalls you get to see just how big a issue it is.

    A trojan i wont name came out a few weeks ago which uses DLL injection really well :huh:

    Anyway your making me ramble :p


    You may want to consider it, i know having the hardware in place is great but you have limted control over the apps that get out to the internet with that kind of device.

    You need to use a software firewall with a router to keep things from getting out - I am using ZAP with mine only because it is integrated with linksys ..

    Is it also integratable with the Linksys VPN routers? I saw a firmware screenshot that shows the integration, but when I downloaded the newest firmware for my router it doesn't have the options. Could you shed some more light on this, please?

    The firewall router is only to keep things from coming in - I have found in port probes that it does'nt keep everything out, this could be because I have DMZ enabled ...

    But as for things getting out of your system you will still need a software firewall .. You will find in the security settings of your router ZAP and Pc-Cillan ... ZAP you will need to put the key in for it to work ... then you just install it onto your system and run it as a normal firewall ..

    make sure you have the latest firmware also ... it does work with VPN routers, that is what mine is ..

    A router should keep out those incoming packets ... disable DMZ and you should be fine.

    Yeah, I need to enable DMZ when I use Messenger for video conversations. Other than that, it's always disabled.

    Here are the pics with my router ..

    Not having it in your router though should'nt really matter - Youcan still use a software firewall ... it will do the same thing ..

    - A firewall router can block both incomming and outgoing traffic on a network level.
    - A (local) software firewall is needed to block traffic on an application level (app by app).

    I get by with a firewall router (to block for instance Windows shares) and a well updated Anti-Virus software. With good AV, anti-spyware and common sense you won't need the extra firewall. IMHO.
