eth0?? That's the wired ethernet device, not wireless(?)

These seems to be correct, if you intend to kick out all associated
(wireless) stations and in the future allow only station with hwaddr
01:02:03:04:05:06 to authenticate in the future. If you had any
associated stations before issuing these commands, they should be
deauthenticated and no frames should be accepted from them.

Ping from which host? If you are pinging from a station associated to
the wireless device (wlan0), it should not be able to ping any hosts in
eth0 after this (assuming you do not have another AP that would allow
this, etc.).
