Hi All.
At home I have a PC that has RouterOS installed on it, and I have connected my wife's computer up so that she is using PPPoE thru the RouterOS machine to access the internet.
I am not sure why, but she can also access my internal network address too, which is fine so she can access the mail server to get her mail.

I have been keeping an eye on the traffic usage, and I am surprised to see that in the last 15 or so days her connection had generated 450MB of traffic! She does not download anything off the web, and only uses the computer for a small bit of websurfing and email....oh and the kids do play some of the Flash games on http://www.hit-entertainment.com but thats not a lot of traffic either (2-300kb).
Here PC is also clean of viruses and trojons, so I am at a loss to explain this amount of traffic use. Is it pick up local network traffic and counting that?

Thanks, Jeremy
