Remote Access Server
Host Name Resolution

Quote Server CN
Enclose the server CN in quotes. Can help if your server CN contains spaces and certain clients cannot parse the server CN. Some clients have problems parsing the CN with quotes. Use only as needed.
Certificate Export Options
Use Microsoft Certificate Storage instead of local files.
Use a password to protect the pkcs12 file contents or key in Viscosity bundle.
Use HTTP Proxy
Use HTTP proxy to communicate with the server.

Management Interface
OpenVPNManager
This will change the generated .ovpn configuration to allow for usage of the management interface. And include the OpenVPNManager program in the "Windows Installers". With this OpenVPN can be used also by non-administrator users. This is also usefull for Windows7/Vista systems where elevated permissions are needed to add routes to the system.
