Anyways=2C- Today i got some time to play around and i tried to configure t=
he machine as bridge.

I added device if_bridge to kernel=20

then i added the code to the rc.conf

=20

cloned_interfaces=3D"bridge0"
ifconfig_bridge0=3D"addm sk0 addm sk1 up"
ifconfig_sk0=3D"up"
ifconfig_sk1=3D"up"

now=2C i dun have any network address assigned to any of the interface and =
connect the two lan cards to two other machines and try to ping those machi=
nes from each other. but no success.=20

=20

... do you think=2C this is as expected..? (i think bridge does not need to=
 have any IP address..)
