There's a project called 'vimage' which adds a separate virtual forwarding

can do that.

Yes this should work with a virtualized stack - all the "outsied" interfaces
in each jail / virtual stack could be simply bridged together using netgraph
which is virtualization-agnostic, i.e. a global facility in the current
implementation of "vimage".

Of course a significant problem might be that the stack virtualization patches
exist only for FreeBSD 4.x, but there's a very good chance that a formal
project aimed at bringing vimage into sync with 6.x and -CURRENT could start
shortly...

Also, what would really suit him is a netgraph IP interface node - i.e.
something which takes raw ethernet frames from the interface, performs IP
encapsulation/decapsulation and ARP - and an IP forwarding node with its own
forwarding table. Has anyone done any work in that area? It would be really
cool for VPN edge routing, for example.

Brian.
