I'm running 2.1.0 on a machine with a permanent 28.8 internet connection. Tcpdump works just fine (I do have a kernel with bpf devices). I do not get any "bpf attached" messages at bootime, maybe the newer releases do this. Tcpdump is smart enough to see that tun0 is my primary interface so just typing "tcpdump" does the right thing. - Mike
