Dear Expert,

Does anyone know by using the pix version 6.3(5) can block or deny a particular MAC address to pass thru pix?

I have this problem too.

PIX 6.x does not have the Layer 2 MAC ACL feature. So, there is no straight-forward way of doing this.

The only think that may work (but it is a bit of a kludge) would be to enable aaa authentication/authorization for through traffic, and then use a mac-list to exclude everyone but the MAC you want to deny. Actually, you can just use a specific deny followed by a permit for everyone else. That would require the specific MAC to be authenticated/authorized. ...just a thought, but I'm not sure I would recommend it. It would depend on the amount of traffic the PIX was passing.

Sincerely,

David.
