I sniff with wireshark in the interface on which 192.168.0.10
I sniff all the traffic without any filter such as destination or source.
I don't see any ESP packets. I expected some ESP traffic.
I suspected that something is wrong with the setup as described in
my post, but it seems to me that there is no error there.
So I am still confused and do not know what is wrong here
and why don't I see ESP packets at all.
