How do i block limewire, kazaa etc on my network?

[Nilsen]

I have a neighbour that gets to borrow my internet for school etc, but i dont want her to use limewire, kazaa and other software like that.   

How can i block those kinds of programs from going through my router?

Any ideas?

Depends on what kind of router you have.  What Brand/Model is it?  El Cheapos or older ones may not give you the options to do it.  Some newer or nicer ones can.

Some routers allow you to block domains, but most likely you should find out what ports those apps use and block those ports.

She's cheating on me...

Not a cheapo router. Its a... dlink dir-655

Has alot of options for blocking stuff, but not apps i think. Only website, ports and IP addresses

Just do a google search for the ports used by the programs you don't want her using and block those ports.

cross check them and make sure they aren't used for common things she might need though.

Sounds like thats the only option i have yes.

I would put this in the hardware software forum. There's folks that look at that forum every day just to help or gleam some knowledge.

You could use a program call Getif, believe it freeware. That should tell you every port being used, and what application and ip address. Once you know which ones to block you could do that, But at the end of the day if she's actually opened up sharing then theres no telling how many IP's are gonna connect to you.

Does said neighbor borrow your computer, or just internet access thru your wireless router?

[Nilsen]

just access so i cant put anything on her puter

You can block the domains of popular filesharing sites, which will prevent her from using a web browser to look for the files.  The router ought to have a menu where you can just add either entire domain names or even just keywords (like pirate, porn, etc) and it will block web access to any site with that text in the address.

As for the ports, that's a lot more difficult.  You can configure bittorrent to use ANY range of ports, so blocking it is somewhat problematic.

You might actually need to go the opposite route, and block ALL ports except for commonly used "legit" ones like 80 for web, 21 (ftp?), etc.  That is sort of how windows firewall works, where it *attempts* to block inbound traffic to all ports except ones you have explicitly left open.  That might be the only way to block the filesharing programs since they know people will attempt to block their use.

Of course, if she's smart she'll just configure bittorrent/kazaa or whatever to use port 80 and then you're hosed, but if you detect that she's doing that then she's busted and just cut off her access and give her a stern lecture about betraying trust, etc

[Nilsen]

Yup eagl. I have blocked the majority of the websites and torrent sites for her. On my router you can set rules for each of the MAC addresses on the network so that is done. The problem lies with mainly kazaa and limewire that i know she uses.

Doesnt bother me that she DL/steals so much but when she gets going and uploads stuff aswell it can affect my AH gaming hehe.

One intermediate alternative is to block the listen port. That won't stop her but it'll kill her download speeds by quite a bit.

IIRC (from my college dorm days), Kazaa and the likes will tunnel its traffic along port 80 (HTTP, web browsing).  You'd need something to 'sniff' the packets.
