If you want a device to only be available locally - block the traffic to/from that device. Or block if from acquiring a public address and leave it as link-local only [most people will, I think, just choose the first options - like they do now when they want to block a device]. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
