For obtaining a fast firewall with netmap: You need to adapt a firewall software to use netmap. The first example of such firewall is netmap-ipfw ( https://code.google.com/p/netmap-ipfw/), but as a userland firewall separated from the host IP stack, it can be used as a "bridge-firewall" only and not a classical "router-firewall". I don't know the status of the current work of adapting a full IP routing stack to netmap, but it should be not easy: Some company like 6wind ( http://www.6wind.com/) seems dedicated to this task (in their case with Intel DPDK).
