- Better encryption (see below)
- TLS 1.2 only
- AES-256-CBC and SHA-512 for HMAC (instead of BF-128-CBC and SHA1)
- Run server in unprivileged mode, reducing risks to the system
- TLS-auth to help [thwart DoS attacks](https://openvpn.net/index.php/open-source/documentation/howto.html#security) and provide a 2nd line of defense to the TLS channel.

- Nearest [OpenNIC DNS Servers](https://www.opennicproject.org/)
