I am trying to implement a VPN PPTP server on Win2K server using RRAS in a workgroup. AD is not installed. The system has 2 NICs. The first one is connected directly to the internet and has a public IP address via DHCP. The second NIC is connected via another ISP using a Netopia router that is mapping public IPs to the private internal addresses it is assigning via DHCP. It has no security. At present this nic has a 192.168.1.27 address and a public address is mapped to it. My problem is when I try to connect using a Win2K pro workstation remotely through the 1st NIC, it begins authentication and then stops responding and gives a 721 error. Please advise.

Make sure the firmware on the netopia is up to date.

Also make sure vpn passthrough is enabled on the remote connection router.

The router is utilizing IP maps which map the public IPs to the private internal addresses. So in my case, the public IP is mapped to 192.168.1.27. There is no blocking of ports whatsoever. The machine at that address is wide open.

I thought the first nic was connected directly to the internet? You are running no domain just workgroup?

The first nic has a public address via dhcp from Comcast. The second is statically assigned an 192.168.1.27 address and the router does a static IP map to that address.

Are you running service pack 3 or 4 on the client? I wonder if you are connecting via the comcast interface and the server is replying via the netopia interface, the vpn client sees this as a different ip address and drops the packet.  Kind of like this situation
