Is there a way to configure Linux to forward packets only if the IP address validates against a IP address-to MAC table?
I have several machines which have priviledges based on their IP address like higher bandwidth, outgoing SMTP, etc. Now it is entirely possible, that when any of these machines are down (typcally at the end of the day or early morning), someone in the office can statically set their IP address to any of these and enjoy these priviledges. How do I validate IP addresses before routing? I know I can do this by creating a userspace netfilter process which marks packets after validation, but is there any out of the box solution? - Sandip -- Sandip Bhattacharya * Puroga Technologies * [EMAIL PROTECTED] Work: http://www.puroga.com * Home/Blog: http://www.sandipb.net/blog PGP/GPG Signature: 51A4 6C57 4BC6 8C82 6A65 AE78 B1A1 2280 A129 0FF3 ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
