We have WinNt 4.0 Server as an PDC and I'm trying to configure VPN on a Win2000 Advance Server which is on the domain as a standalone. I try to enable the remote access and then I go thru all the steps. I choose VPN server from the listing at the time of setup and then next and at the Internet connection I choose the Network adapter which is currently on the network, but when I choose that adapter it gives me error message sayiong that atleast one adapter needs to be connected to the private network. So I choose No Connection and it moves over to the next step. Then I configure manually the IP addresse to be assigned to the client from the DHCP server. When I finish the whole setup and try to VPN in to the server I get an Error 800 message. I cannot connect from outside thru the internet. I use DSL for the internet from home for the VPN. We have a SonicFirewall as an router, Please advice if I need to make any changes on the firewall or if I need any two network cards on the VPN server. I read some article on your website and tried few things but no luck. So any help will be very appreciated. I would like if you can send me step by step configuration for VPN configuration.
