Hi list,
during the last days I read some stuff regarding ipfilter and the netbsd =
ethernetbridge devices.
Some quotes state, that using this combination is not possible.
I found several points of aquivalence with OpenBSD/pf and bridging.
In the manual for OpenBSD/pf, they state that one has to filter on the =
devices, that build the bridge (for example fxp0 and fxp1 -> bridge0, =
filtering on fxp0 and fxp1).
Isn't that possible on NetBSD and ipfilter, too ?

Any comment is welcome.
