this is not secure; it will leak your ipv6 address by default. use openvpn's ipv6 features to route ipv6 traffic as well[0]. using openvpn ipv6 is a PITA on digitalocean because they only provide a /124, when openvpn requires at least a /112. you can get around this using ip6tables to route a /112 address range you don't actually have access to, and the only consequence will be a loopback if you try to access one of the digitalocean IPs you are claiming to have in your available pool while connected to the VPN.
also, 1024 dh prime is unsafe depending on your threat model[1]. use 2048 if nation states bother you, or 4096 if truly paranoid or at high risk / performance isn't an issue. no reason not to bump up the RSA keys too.
