when client is behind firewall via nat to internet, and server has dynamic ip, I don't think keepalive will help. since the changed server can not connect to client, it needs client to initial the connection. under openvpn, keepalive can detect broken link and try to restart itself, then client can reconnect to server automatically.
If both sides are using keep alives it could help. It won't work if both sides change IP addresses between keep alives. And if the client is turned off when the server changes IP addresses that is going to apply.
