You didn't write on which host you captured the packets with Wireshark. If it
was on the same host on which strongSwan was running then this behavior is
normal. It is a quirk of the Linux kernel that for incoming traffic both the
ESP packet and the decrypted payload are captured and that for outgoing traffic
only encrypted ESP packets are visible.
