Router Stealing MB's

[nugpot]

I have been using Antibody's excellent little utility and have noticed that on days where none of the computers in my house are on (Telkom router stays on), the SAIX stats utility reports anything up to 800k uploaded and up to 13MB downloaded. Switching the router off reduces this to zero.

Can it be that the router uses this much traffic to keep the line alive for 24 hours? We're looking at 400MB overhead per month when no real traffic is requested.

Can somebody cleverer than me please comment.

maybe trojan/virus attacks. They get to your router and then have nowhere to go. SInce you are logged on to the network it uses up YOUR bandwith. If you switch the router off, you are no longer logged onto the network and so you use no bandwith.

I think ...

Enable the modem's firewall logs, if it has such a thing. 13MB per day in portscans/ect is nothing to worry about (well, not as far as bandwidth goes).

On days where a specific IP gets targeted in a scripted attack (the tiny fragments attack seems popular), I've seen clients reach their cap in a day, i.e. 3GB worth of attack traffic in a day.

Now imagine you're using an ADSL modem idrectly on your PC without any firewall software.....
