In linux kernel since version 2.6.12  
iptables is a general, extensible packet identification framework.
The packet filtering and full NAT (masquerading, port forwarding,
etc) subsystems now use this: say `Y' or `M' here if you want to use
either of those.

To compile it as a module, choose M here. If unsure, say N.
