hello
I have a problem with my router
I know for sure that the system records the mac add fastweb of everything that occurs in the central
I cuase this a problem because whenever I connect a pc with mac add different
always asks me to enter the tax code
fastweb because the system recognizes it as if I changed the modem
but in reality the mac add that presents itself and that of my pc.

I enabled the nat but this cmq let the mac add all the network adapters that connect to the router

how can I do to hide these mac add?
how can I avoid that I always ask you to insert the mac add
which settings I can set?

thanks
