Dear Dippas,
Thanks for your reply!
Well I think I was mixing up 2 different topics here...
1. The SBS server will act as a webserver and not as terminal- or exchange server, nor as domain controller. So I'd like to configure the server being part of a workgroup, but not acting as domain controller. So far I could not find any option to configure SBS like Windows Server 2003 Standard Edition.
2. For enabling VPN connections on SBS, Routing and RAS is enabled on SBS. But I'd also liek to activate the Windows Firewall. If RAS is enabled, using Windows Firewall is not possible, but it is possible to configure the RAS Firewall. However, when using the RAS Firewall, I have to determine one specific IP address for each protocol. While this is Ok for Remote Desktop, FTP, for http and https it is not. Because the SBS is acting as a webserver, there may be dozens of different IP addresses I have to add to the RAS Firewall, e.g. 192.168.0.*, but howto?
