The Remote Access Server (RAS) allows users to 'dial-up" via Telephone. The Client connects to the "intranet" via a RAS Server on the private network. When the client connects to the RAS Server, it will be assigned an address in the "private network". This will allow the client to connect to a "private network" o intranet. You have to setup a RAS server on the same network (intranet) as the SCADA Node . The RAS server could be the SCADA Node or another computer on the intranet. RAS is a standard feature in Windows 2000 Server.
To create a simple remote access server for a Windows 2000 Server-based computer that belongs to a workgroup and not a domain. The resulting server allows users with local accounts to connect by using dial-up, virtual private network (VPN), or direct (Infrared or parallel ports) connections. However, only limited authentication methods are supported by Incoming Connections Server. Clients can connect by using only MSCHAP or MSCHAPv2 authentication. A default Remote Access Policy is applied.
