Configuration Examples OpenCom X320 in a Serverless LAN Note: Workstation PCs automatically add a domain name to URLs without a dot. You specify this domain name in the Configurator. For example, if you have configured "firm.co.uk" as the domain name, an access request for "www.firm.co.uk" will be interpreted as a local DNS request which does not lead to the establishment of an Internet connection. For this reason, you should choose a name which is not used in the Internet as the domain name ("firm-opencom.co.uk" for example). 7.3.3 RAS Access You can establish a connection to the OpenCom X320 from an external PC via a VPN connection or via an ISDN card. VPN (Virtual Private Networking) is a technology to connect an external PC over an existing Internet access using a secured and encrypted data connection. A prerequisite is the permanent internet access of the OpenCom X320. As an alternative, the "ISP trigger call" can be configured. To secure the data connection, the protocols PPTP and IPSEC are available. PPTP encryption is optional. The necessary IP settings are transmitted by the OpenCom X320 on establishment of the connection. The computer that has dialled in has access to all services in the LAN that can be used via the IP protocol. The authorisation for RAS access is set up in the Configurator via the User Manager: User Groups menu. The technical properties of the connection can be configured in the Configurator via the NET Configuration: RAS menu. Select one of the offered connection protocols (ISDN, PPTP or IPSEC). Further information can be found in the online help of the web console. In a serverless LAN, Windows uses the NetBIOS protocol for accessing files and printers via the network environment. NetBIOS can use NetBEUI, IPX/SPX or IP as the transport protocol. In the network environment, you can only access files and printers on workstations using IP for NetBIOS. 83
