Hello, All!
FreeBSD 10.3-RELEASE-p7 r304924M
VM under hyperv
simple ipfw rules
hn0: inet 192.168.1.254/24 (connected to wan via 192.168.1.1 router)
hn1: inet 192.168.2.2/24 status: no carrier
Then I add fake route (via not used interface):
and fwd rule begin to works
Is it right behavior? It seems like I can't push packet to any interface if I haven't default route.
I made some experiments: add out, out xmit hn0 without positive result.
