Yes, it looks more natural to do it at the ip level (this should be at tcp
level, but the
routing does not go so high). However, forgive me if I'm wrong here (I am
new to netbsd & ipfilter) but doesn't IPF shortcut ip_output sometimes ?
(the fastroute stuff)
I had the impression that it was talking directly to the interface, in this
If this is so, then the ipfilter user will not benefit this feature ...
