Comment 2 for bug 1938571

Hello
It's still not working under xena.
My workaround:

modify in neutron_l3_agent container
/var/lib/kolla/venv/lib/python3.6/site-packages/neutron_vpnaas/services/vpn/device_drivers/libreswan_ipsec.py
    def start_pluto(self):
        cmd = ['pluto',
               '--use-netkey', #delete it
               '--uniqueids']

/var/lib/kolla/venv/lib/python3.6/site-packages/neutron_vpnaas/services/vpn/device_drivers/template/openswan/ipsec.conf.template
config setup
    #nat_traversal=yes # hash it
