So...computers behind a router are totally invisible and untouchable by the internet?

ya, with all the ports closed, yes they are.

How do you close port 113?

lol, it is "closed", but it is only closed, router answres to it.

To fix this, i forwarded it to my computer, then blocked it with windows XP's firewall...
i can't remember, but i may have also been able to just forward it to a random ip address and then it wouldn't be responded to, but i can't remember...

wait like 5 miutes and ill tell you if that works...

edit: ya, it works that way. I set it to forward to ip 192.168.0.89. ran the test @ https://grc.com/x/ne.dll?bh0bkyd2 and it came up as "stealthed."

But i failed teh test becuase of my open bittorrent and ftp ports lol.

But "stealthed" is not the same as "closed" is it?
When I take that test, I have a completely green ("closed") board except for port 113.
Supposedly ZA is supposed to adaptively learn to show that port as "closed", but my ZA must be a poor student cause it never does.
I'm not particularly worried about it, most folks seem to think it isn't a big deal...I was just curious.

If you read the instructions somewhere on that page you will see that closed is good, but stealthed is better.

Closed means that the computer&#092;your router&#092;something at that IP is answering to that port. It is saying it is closed, but it is still responding. This tells the hacker that there is something at this IP address.

If it is stealthed it means that the computer just didn&#39;t answer at all to teh port. So the hacker will thik there is nothing at all at this IP adress, and move on...

atleast that is how i understand it.

You&#39;re right, I had it backwards.

I get all "stealthed" with port 113 standing out as "closed".
Can&#39;t figure out how to stealth it.

Yes, i had that exact problem with ZA. If you enable teh windows firewall, it blocks it.

oi rossco and clocker...stop hijacking my thread&#33;&#33;&#33;

[clocker]

We didn&#39;t "hijack" it, we merely expanded it&#39;s scope.

Now it&#39;s blown up.

Out of curiosity...
If one is behind a router ( hence, a hardware firewall) does one still need a software firewall on each computer hooked to it?

A software firewall can be usefull to warn you when a software application is trying to send signals outbound from your PC to the internet. Lots of software likes to &#39;call home&#39; and a software firewall will alert you and give you a choice to block it or not.
