Network Filter Off really off?

Hi gang,

I just realized that even when turning "Network Filter" to off, there's still internet traffic going on (constant download of 0.2-0.3 KB/s). Shouldn't all Internet traffic be stopped when we click on "Stop Network Filter"?

Note I monitor my connections/traffic with PeakHour and just to test it's accuracy, I've disconnected my WAN and traffic went down to 0KB/s.

So LS still lets some traffic thru, why?

Thxs
