Is that possible? It is easy to limit the MAC <-> IP address mapping, no need for a firewall, ip neigh is enough. Then it is easy to limit SSH to a certain IP address. Of course, it only works if the host is on the same local network. And of course, it is absolutely not an efficient security measure. Regards, -- Nicolas George
