Hello Jose,

Is there a firewall active on either of the host? Do the traffic counters, which are shown in the output of "ipsec statusall", increment?

I have tried this with both StrongSwan 4.5.2 and 5.2.0 and have the same result, so I'm sure it's my configuration. After bringing up the the connection everything negotiates as expected, and the final line of ipsec status all is machinetun{1}:   10.128.0.0/16 === 192.168.250.0/24 where machinetun is the connection 10.128.0.0/16 is a private network on DigitalOcean and the 192.168.250.0/24 is a private network on my machine. My logs show the CHILD_SA being established and rekeyed as expected, with keep alive packets going out frequently, and nothing to suggest a problem.
