tcpdump with Linux 2.6 and ipsec/ESP

[Michael Mueller <m.mueller99 () kay-mueller de>]

Hi,

On Linux 2.6 Intel with a ipsec connection in tunnel mode I found that 
tcpdump shows incoming and outgoing ESP packets as expected. It also 
shows the incoming packets after they are decrypted (starting from 
behind the ESP header). But it does not show outgoing unencrypted 
packets which is a pity. (I had to use tcpdump -E, which needed a fix 
first. See my earlier posting.)

Is this a Linux or tcpdump / libpcap problem? Does anybody have some 
further details about it? Is there a more appropriate Linux list to send 
this question to?
