DD-WRT WAN Data Usage by IP Address

redmaxx 21,160 1,591 February 3, 2012 at 12:34 PM
Cox recently rolled out data usage monitoring in my area and since I was over, I upgraded the plan, which also upgrades my speed. The trouble is, now I'm over limit again. Cox is all that's out here and while they haven't bothered me so far, I don't need any trouble from them since I rely on my connection for work.

Is there a way to configure DD-WRT to watch WAN data usage by IP address within my network? I can assign static addresses to everything and then I can see which device is using up the most data and plan how to reduce it from there. But right now, all I see is aggregate WAN usage, which doesn't help me (except to see that Cox underreports my data usage compared to DD-WRT).

snmp reporting per interface fed into something like cacti?

Might not be too accurate if you have a lot of internal data flying around

If the goal is to prevent the overall traffic bandwidth from exceeding the service provider limit, setting max bandwidth in QoS might be the way to go. Although it might get 'traffic jam' during rush hours but at least you know cox won't send you the warning message again.

Lots of internal data, so this probably won't work.

Can you elaborate? How would I set it such that I don't go over the limit?

Steve Gibson on password policies [grc.com]: I mean, I don't get this change it every eight weeks. ... It's not as if passwords are traveling by camel after they've been stolen, going to the bad guys, and so there's, like, some weird eight-week window, like, oh, we're going to change your password so that the stale password no longer works. ... And all this does is make IT people despised because users, who are not dumb, they think, why am I - why do I have to do this? What problem is this solving?

well at least on the computers you can at least install something like netmeter.

then you can narrow the rest of the data usage down to the other things.

Does it distinguish between local and internet traffic?

above i siad that it would work to a point that you knew how much each computer you have on is using, but you would have to subtract all computer usage form the total and then your other devices would be using whats left of the total.

there is nothing on dd-wrt that monitors each LAN IP's data usage.

I have no way of knowing how much LAN data each computer is using versus intranet unless some application tells me.

Try DU Meter [hageltech.com]...check the screenshots. It allows both filtering of internet traffic as well as local LAN traffic. I used to use it before Comcast got their stuff straight and got an internet meter that works.

Nice. Looks very useful and not hard to setup. I wish tomato had something similar (monitoring Internet traffic based on individual client)

I vote for DUMeter too. Also I found windows 7 has a "resource manager" hidden as a button inside task manager - performance that gives traffic monitoring based on application which would be very useful to catch suspicious / un-intended network usage.

command line tool netstat is useful sometimes as well. I just noticed from DUmeter showed ~70-80kB/sec of WAN usage for the computer I am using although I have all the startup items disabled (ex. acrobat/java/application update schedulers) and the majority was from firefox since I just started it (and it's already ver10.) so something (might be an add-on - I do have fire.fm installed but I turned it off already) in firefox is definitely doing something that used Internet for 80kB/sec for about 5 min ( 80kB/s x 60sec x5min = 23MB data) that I don't know about.

Of course netcat is still the all-time useful tool..
