Blocking MAC address

[hendyman]

Does anyone know how to block a given MAC address from a tcp/ip network.

 

[Accessdabbler]

By "block" do you mean to hide/spoof the MAC address? Or do you want to prevent the NIC from sending or receiving data?

 

[hendyman]

I'd like to be able to block a nic or series of nic's from sending/receiving data to/from the network

hi,
what means to/from network?
does it men:
the TCP/IP packets generated by those MACs will not go outside of the local network?!

if is it, you have to set something on the router.
what router are you using?
if you have a Linux box as router, you can use `iptables' as firewall.


man iptables

--mac-source [!] address
Match source MAC address. It must be of the form XX:XX:XX:XX:XX:XX. Note that this only makes sense for packets entering the PREROUTING, FORWARD or INPUT chains for packets coming from an ethernet device.
