Hi, I'm trying to open a netmap descriptor to an interface to send packets. However, I don't want to prevent the host to send and receive data (transparent). I don't think this should be hard but I can't figure out how to do this. I tried to run the bridge example in the FreeBSD distribution but even that I can't get to run without stopping the host's networking completely. I tried running ./bridge em0 em0 which, if I understand correctly should open the NIC and host rings and pass the traffic through. As soon as I start it all the networking stops. I tried testing in a VMware VM and on bare-metal with em cards and got the same results with both. Can someone help me? Thanks, David
