I am using ipfilter (is there a better list to ask my question?)

I have a machine that is bridged between the interfaces, when I NAT a
packet the checksum is not recalculated automatically.

Darren gave me a patch, but that is not corresponding to the version
of ipfilter bundled with FreeBSD 4.10.

So does anyone know how to force ip_nat to recalculate the checksum
after it changed a packet in a bridg3d environment?
