My understanding is that I can bind multiple machines running netgraph into
one large netgraph, by using something like ng_ksocket nodes bound with a
tunneling device.
you COULD do that, yes, but the two netgraphs are unaware of each other.
By doing this, is the restriction of one ng_ipfw node per netgraph global to
all of the machines (one, and only one, ng_ipfw node)?
no it's one per machine
If the ng_ksocket nodes
are connected to ng_bridges on both of the machines, will only relevant
network traffic cross the link - or all network traffic?
ng_bridge does MAC address filtering. it only sends no broadcast
packets to teh link where it has seen packets coming from that mac
address.
Can I configure the
link between the two machines so that I can directly connect a netgraph node
on one machine to a node on the other, or must they communicate by the
bridge-tunnel-tunnel-bridge structure?
You are sending the packet out of one netgraph and into another.
how you get the packet there is your business.. you could use two
ng_ether nodes and use a dedicated ethernet as a low latency tunnel.
Thank you.
