Humm, which interface are you tcpdumping ?
I chose to use gif, to encapsulate RFC1918 packets onto the Internet.
Then I use IPSec, in transport mode, to encrypt traffic (using ESP after racoon
IKE), between the two hosts with public IP address.
So I can see encrypted packets only on the NIC interface, not on gif0.
