If you have multiple interfaces, a broadcast to 255.255.255.255

I know it is kind of crude but it works in my case :-)
In our case, it's being run before *any* interface has

The short answer is no, you can't, in_pcb turns 255.255.255.255 into
the primary interface's broadcast address.
I doubt this is actually useful behavior, but that's not what you
asked =)

Ok, sounds stupid right, well here is a bit of background. My friend and
I have an IPSEC tunnel in between our two private networks connected by BSD

you can use netgraph to make a virtual bridge
see /usr/share/examples/netgraph for an example of a single bridge.
attach one of the bridge hooks on each site to an ng_socket node that
has made a udp vpn..
see the vpn example for that..
by combining both the bridge and vpn examples you can hook
Hey,
Thanks for the response. I will look into netgraph then. I was thinking
it could be useful to have flexable utility that could be used to bridge
distant broadcast domains ( w/filtering ). The home-grown thingy is an
exercise to learn more about unix programming. Most of my experience is
