I want to set up a bridging firewall, meaning a firewall that has no 
IP address and simply resides between the main default router (a 
combo DSL modem/router box) and the rest of the net. The IPF HowTo 
indicates this can be kind of done with OpenBSD. Can this be done 
with ipf under NetBSD? Or, is there some other firewall package under 
NetBSD that does this? I don't need much out of this box, just some 
simple host blocking and some NATP for some boxes.
