Internet sharing

Hi there,
I'm on an adsl2 plan with exetel and running a dynalink RTA1046VW modem,I live in a shared house with my partner and a friend and we all share the one internet connection,two of us with laptops connecting wirelessly and my partner on a desktop connecting thruogh LAN.
I have had a few discussions with our friend as he at times will hog the net and we cannot do a thing and also at times tends to download movies and music and can run us over our download limit,after we talk it over he backs off,but after a while tends to get stuck into the downloading fairly severe thinking I am not aware.
I pay for the service and I dont want any money from our friend as it will then open the floodgates for net hogging as far as I am concerned.
My question is.....Is there a way by either software or modem settings I can slow this person down,restrict his usage even to what amounts he can download and only have access to one quarter of the total net speed is what I'm trying to say.
Please be aware I am computer literate but not in the advanced class of users.
Thank You....CheerZ...pizz

I believe you may be able to set your router to use OpenDNS to set some sort of rules, I'm not really a fan of using 3rd party DNS though

The Dynalink hasn't got what you need in the browser interface. Like most modems it is a single board computer running embedded MontaVista Linux who don't provide manuals. Any Linux box, including the Dynalink on it's telnet interface, can be configured as a gateway, but it is emphatically not elementary stuff (iptables etc), and I'd hate to see you brick it, so a few groups have preconfigured a gateway for you, at no cost, but you will need an unused computer of very modest ability (read old clunker with two ethernet ports). This is the type of solution used in businesses. The Dynalink and your Exetel login are given non-default passwords and the Dynalink is put in bridge mode to the computer/router.

Look up, and These are routers in their own right to put at the front of your LAN. You make the rules about how much data and what kind.

Clear is aimed mainly at system administrators, while untangle is positioned mostly for ordinary Windows users and the underlying Linux is well hidden. Check out the demo videos at Each user can be individually controlled or virus checked.

If you hunt around there are a few others. Even ordinary desktop Linux distros are good for the job, and the instructions for intermediate users to configure desktop and server Linux, eg Ubuntu, as routers are online in the help pages. (firewall, DNS, DHCP, and network interface need set up, basics are at

What this does for household trust I am not game to predict, but it works.

Look into a router with QoS or RSVP and how you can implement prioitisation and reservation to serve what you need best.

The Cisco Linksys WAG120N and WAG320N appear to implement QoS however I haven't had the chance to test them out. More interested in the QoS for VoIP however it may serve your purpose.

Otherwise tell him you don't want to pay extra on your connection and activate the shaping option.

Wouldn't router bandwidth control be a bit too unfriendly for household harmony though? It's not really a prioritisation issue, rather here's your full speed share and that's all.

OpenDNS can block pages, etc but can't throttle or manage individual connections.

Linux based gateways PCs are the most flexible, lots of choices, and open source. They will, however, require dedicated hardware.

I think one of the best options is a WRT54G or similar device to replace your Dynalink router / modem and upgrade it to run Tomatoor dd-WRT, etc. These are open source modem firmware that provides a great deal of bandwidth prioritisation and throttling controls.
