No. Everything is encrypted. And when using the native 2.6 ipsec stack, there
are no virtual ipsecX interfaces.
You can't run tcpdump on the host to see whether or not the 2.6 ipsec stack
encryps the packets, since there are encrypted after the point where tcpdump
can read them. Use a box in the middle or the other endpoint to confirm the
crypto is still working.
