However, # if you are using it as an as-needed filter for specific problems as # they arise, then this may be for you.

Because of this great care is required when # crafting the ruleset. # # IPFIREWALL_NAT adds support for in kernel nat in ipfw, and it requires # LIBALIAS. To build an ipfw kld with nat support enabled, add=20 # "CFLAGS+=3D -DIPFIREWALL_NAT" to your make.conf. # # IPSTEALTH enables code to support stealth forwarding (i.e., forwarding # packets without touching the TTL).
