Hi there! I'm using OS X 10.9 and standard apple ipsec connection. After connection I see utun0 interface is active. But when I use command "tcpdump -ni utun0" i haven't see any captured traffic. If I use standard L2TP connection and interface ppp0, I see a traffic and it's work perfect. Why it doesn't work with tunnel interfaces? Thanks! asked 10 Dec '13, 21:25  Yevgeniy Luc... |
One Answer:
see the other question about utun0.
Apparently Apple did not fix that 'problem'. So, please check the status of Apple Bug-ID: 9699332 (the other user filed that bug report). Regards answered 09 Mar '14, 03:20  Kurt Knochner ♦ |
I have this problem too running OSX 10.9.2, no traffic seen on utun0. I've checked with other Mac users I work with and they also cannot capture on utun0 running Mavericks.
