Who's using my router?

UNIXMAN
Interesting, I thought that the M A C address filter function in the router settings only allowed those computers which had the M A C addresses listed and locked into the router access to the router.
Following some not so deep thought I now understand that a particular listed filtered computer sends out its MAC unencrypted, so someone could capture that address and use it to by-pass the MAC filtering.

Cheers
