I'm looking for a VPN server solution that allows clients to use the native Windows Vista VPN client. Main reason is cost, since I am in a startup with little funds and not having to spend $50 per client for software, as well as not having to install any more software, is very appealing to me.
The only thing this will function is the VPN server. I already have a firewall solution, so this is of no importance to me. From what I understand, Vista's client will not connect on an IPSec VPN connection, which is what my firewall provides.
I do not want to expose SQL Server externally, this is the main reason I want VPN. Is this something Windows Server 2003 could handle? Regardless, it would be cheaper finding a smaller hardware firewall solution I would think.
