3. If I want to use VPN to connect my 4 domains, which device do I need? Model number? I know I can assign the public IP address to one of my server?s NICs to let this NIC wait for VPN calls but I don?t think it is secure. Could I use a device such as route to let the VPN calls go to the router first then let the router route the VPN package to my server or I can use a hardware device called VPN server? Which brand and model number? My client domain will use ADSL (dynamic IP address), is there any device can start a VPN call to my server? Model number? If I use VPN router in each domain then I will never need to use the Windows 2000 VPN function because the VPN devices will be dealt with the VPN connection by itself?

Any idea will be appreciated. Thank you!
