Hello,

I own a cisco 1811 router. There's is no wi-fi built-in feature on the router and I do not use wi-fi in my network.

I would like ton configure the router with a "mac filter" for all ethernet connection, like linksys router do to permit wi-fi connection.

I would like to deny all, and permit specific client using their mac, there's no problems for me to allow each switch in the network + clients.

I think I can accomplish this using the NAC fonction of the router but I have to use a RADUIS server but I would like to avoid that. There's only 12 clients in the network.

Thanks for helping.

Filtering for MAC address is done at the switch level (Layer 2)

You have to configure each port to accept only one MAC address.

The command you want is switchport port-security.

I don't think your router will support that command, but you can give it a shot.

Great ! thank you for the hints
