Nope. Neither netgraph nor bridge(4) produce a pseudo-interface. Unfortunately. It would have solved the problem I was discussing with you (alas, I found a y2k thread, in which Archie and you were also present, about that very same problem). Netgraph's ng_iface is not enough, because it's much more limitted. > > > >>I had an older set of patches (4.x?) that implemented a bridgeX interface >>that saw all of the packets bridged by the bridge.
