I have just setup a LAN at home with the following specifications:


A wireless router (linksys wrt120n) connected by an ethernet cable to a desktop server.
Desktop server running Windows Server 2008 R2, no antivirus or third party firewall installed yet.
Clients on this network are laptops and cellphones connecting via Wi-Fi.
Internet access is via a usb EVDO modem connected to the desktop server and shared via Internet Connection Sharing.
Static IPs are as follows: desktop--> 192.168.137.1, wrt120n router---> 192.168.137.2
The rest of the IPs are assigned by the ICS DHCP on the desktop.


Problem is there are some clients that are running torrents and large downloads, which are starving off everyone from smooth internet browsing. How do I control this. I have tried blocking ports 999-65535 from accessing the network via the router and also tried the same by blocking them via the desktop's windows' firewall but to no avail. Setting up QoS priorities on the router is not working neither.
Preferably I would like to control this without installing any 3rd party software, however if need be, please tell me the best software I can use to achieve this feat...

Thanks in advance

You should be used du meter

Seriously, if this is a home network, find them and unplug them and don't allow them back on until they agree not to be so anti-social with the internet connection.

You can also assign them a fixed IP... and turn off the DHCP server... and also authenticate based on the unique ID of the lan port. So they can't simply change the IP address.

I am assuming you know how to set up the QoS correctly giving P2P apps the lowest priority.

Manual IPs will mean that every time anyone goes off to use their laptops elswhere they have to reconfigure their networking settings which is too much work for anyone on the go. I am using a Wireless router, didn't know there are individual ports for each user connected to it via wi-fi.

My setup seems not to support QoS, the modem is connected to the Desktop not the router. I tried the QoS and it was no use. However if there is another way of setting up the QoS on the server itself then please enlighten me.
@Curlyben I know that option, but I want to learn the more technical methods not the social ones...
@Ahmadpour what is that?


please note, the specs and network setup i provided in my question.
