OpenVPN Support Forum

As I came into trouble allowing Incoming Dial-up clients together with the working OpenVPN service on the same server, I searched the net for answers, which came from old board on openvpn.net.

So the problem consists in that it is recommended to disable Routing and Remote Access Service (RRAS) when OpenVPN is installed. The reason for this is, that RRAS interferes with dynamic network addition. But, as I didn't find a 3rd solution for dial-up service to use, I had to use RRAS. It came up that OpenVPN can't add routes using IPAPI method (which is default) when RRAS is running.

The selution found here http://openvpn.net/archive/openvpn-user ... 00066.html is:

On a server I use 'route-method exe' in order to add routes through the shell instead of IPAPI.
On a client I use 'route-method exe' and 'route-delay 10' for the same reason.

So, using route-method exe allowed OpenVPN to add routes to routing table with RRAS running. Why via IPAPI isn't possible remain misterious, as microsoft does not asnwer to 3rd party software problems as they think it is.
