You'd have to tell us: a) what operating system (I'm guessing Linux). b) what IPsec stack you are using (many operating systems have multiple stacks) c) what the arrangement of tunnels and IPsec SAs you have, so that we'd know what packets you think you will see on "eth0" Different IPsec stacks for Linux have very different properties about how the packets flow, and what connections are available for tcpdump. -- ] He who is tired of Weird Al is tired of life! | firewalls [ ] Michael Richardson, Sandelman Software Works, Ottawa, ON |net architect[ ] mcr () sandelman ottawa on ca http://www.sandelman.ottawa.on.ca/ |device driver[ Kyoto Plus: watch the video <http://www.youtube.com/watch?v=kzx1ycLXQSE> then sign the petition. - This is the tcpdump-workers list.
