I use this scenario for test netmap-based ipfw with real NICs. =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D sender (eth0:10.10.1.1) DUT (eth0:10.10.1.2) (eth1:10.10.2.2) receiver(10.10.2.3:eth0) ./pkt-gen -i eth0 -f rx -------------> ./kipfw netmap:eth0 netmap:eth1 --------------> ./pkt-gen -i eth0 -f tx where sender and receiver connect to DUT directly. =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D I think that kipfw capture packets from DUT's eth0 (which come from sender's eth0) and forward them to it's eth1 (which connect directly to receiver's eth0), after apply policies from ipfw/ipfw. I expect that see packets that pass the ipfw's policies in receiver. Is this scenario and my expects true?!
