> I am not sure if a regression was introduced with this PR #2062, but we have found issues
with this configuration now that we have it in production.
> The core of this change is to change the S2S VPN config from {{auto=start}} to {{auto=route}}.
Read more about this setting here: https://wiki.strongswan.org/projects/strongswan/wiki/ConnSection
> We found there to be issues when using {{auto=start}} for both sides of the connection
as there was problem negotiating the connection. Instead the {{auto=route}} config will only
establish a connection once there is an attempt to send traffic over the connection. In order
to attempt to open the connection as soon as the VPN connection is configured, a ping to the
other side of the connection has been added to establish the connection.
