You don't need to _use_ dummynet, they just happen to come together.

If you only need to implement a firewall then your ipfw rules
will only contain pass/drop actions.

The performance boost comes from using netmap,  thus bypassing the
native network stack and -- if available -- using optimized network
drivers.
