I'm seeing huge amounts of usage at the moment, off peak (4pm midnight) has been around 1.5Gb the last 2 nights.
The problem is that I'm hardly using my internet connection, nothing that warrants 1.5Gb data. I downloaded a couple of programs (avg, a thunderbird update), did a bit of surfing, Mrs SiMania did a bit of surfing and facebooking, twitter.
No P2P, no streaming yet it's hitting 300MB+ data transfer per hour according to networx (which I've got configured to monitor my wan port, I know it's not 100% accurate, but it's pretty indicative) .
Devices connected are a couple of iphones, imac, macbook, 2 windows PCs and Apple TV, only one or 2 are used simultaneously .
Traffic is being shown as mainly web or P2P or other. I've no P2P running, other may be VPN traffic as I was working til 6pm.
Router is a 3COM 3CRWDR101A-75.
Any idea what could be causing so much usage?
Are there any other programs that can use the SNMP service on the router to find out where the traffic is coming from on my network?
I'm running monitoring tools on all my devices that are attached to network at the moment and can't see any excess usage (2-3MB on all devices combined in last 15 minutes), yet networx tells me every minute or so a few more MBs are being downloaded, then I'll see a spike of usage. The received Bytes on my router stats page back this up.
A theory I'd like to throw out there is that there is malicious or otherwise unwanted traffic hitting my WAN interface, but getting blocked by my router firewall and not making it to any device on my LAN, hence me not seeing the usage on any of my devices, but seeing the usage on the WAN interface. Does that sound plausible?

At any given moment in the universe many things happen. Coincidence is a matter of how close these events are in space, time and relationship.

By my reckoning our pro-rata daily usage has magically doubled since we moved to this house on 2nd May - and that's despite only a third of the network that was in the old house being taken out of the packing crates.
In our last house we had six computers, and my work laptop hooked up to a completely unlimited non-Plusnet non-ADSL system where I had full visibility of the traffic - and we rarely used more than 20GB in a 28 day period.
And yet we've managed to receive a warning from PlusNet that we are approaching our utilisation AFTER JUST NINE DAYS. Which is quite remarkable considering that by my reckoning, there's only one laptop out of the entire home network, actually powered on for most of the time.

Surely the clue is in there, somewhere?

It was down to having the DHT option selected in a bittorrent client I use on the iMac called transmission. I disabled it and changed the port it used, traffic stopped pretty soon after that. Usage for today was less than 10% of what it was yesterday.
So moral of the story is, if you use transmission or a.n.other bittorent client, don't use DHT.

I never liked torrents in general for this very reason.
