Thanks, it's clear now.
But it leaves me with another question. Suppose I've got a card
which support tcp offloading. It'll be enabled by default, however,
when i run a firewall which manipulates several fields in the ip and tcp 
header i do not wish the card to perform offloading.
Is it allowed to disable this by somethig like
ifconfig wm0 -ip4csum -tcp4csum -udp4csum link0 media autoselect
or isnt it?
Bye,

Mipam.
