[Openswan Users] tcpdump no outgoing traffic over VPN

Hello to all and happy new year.
I am trying to acquire a tcp dump in a pcap file using the following
/sudo tcpdump -s 0 host HOST_IP -i eth0 -w tcpdump_test.pcap/
The OS is _/Ubuntu 14.04/_ server edition with the */3.13.0-92-generic/*
kernel running on an AWS instance.
I am able to capture incoming traffic from the host to my server but
when I download the pcap file and open it in Wireshark I do not see the
outgoing traffic (neither ESP packets nor clear text).
I have tried to use nflog as described in
but it seems that nflog is not included with the Ubuntu kernel. I am
unable to find a way to see outgoing traffic towards the host in question.
Can anyone please suggest a solution?
Thank you in advance
