A bit of both. Its my project for graduation hence educational, but i have to finish it. so...

I did try the packages from netfilter.org
When i run the DHCP client, i get the foll messages :
May 6 13:33:20 localhost dhclient: socket: Invalid argument - make sure
May 6 13:33:20 localhost dhclient: CONFIG_PACKET (Packet socket) and CONFIG_FILTER
May 6 13:33:20 localhost dhclient: (Socket Filtering) are enabled in your kernel
May 6 13:33:20 localhost dhclient: configuration!
May 6 13:33:20 localhost dhclient:

So does this mean, filtering is enabled and i can run my project?
Thanks

NAME
dhclient.leases - DHCP client lease database DESCRIPTION
The Internet Systems Consortium DHCP client keeps a persistent database of leases that it has acquired that are still valid. The database is a free-form ASCII file containing one valid declaration per lease. If more than one declaration appears for a given lease, the last one in the file is used. The file is written as a log, so this is not an unusual occurrance. The format of the lease declarations is described in dhclient.conf(5). FILES
