Setting up VPN and RRAS on a W2K Server in a Workgroup

[Guest]

I have a win2k server in a workgroup. We have a dedicated ip address on the
external connection and a dedicated ip address on the internal. I have set
up ras with the following settings:

Router is checked
Local area network routing only
Remote Access server
Using Windows Authentication and local policies for users connecting.
I have DHCP enabled

On the router I have port forwarding on ports 1723j, 500 and 47 directing
traffic to the servers internal IP address.

I have the users configured to allow dial in access.

I have this same configuration on a domain controller at another site and it
works flawlessly but on this Workgroup network I am unable to connect. Do
you have any ideas on what could be wrong?

Your help is greatly appreciated.

For a PPTP connection you need to allow access for GRE IP Protocol 47. This
is not the same as a TCP port. On various routers it may be enabled by
turning on something called VPN pass through or by mapping a PPTP service:

Hi Doug,

Thanks for the quick reply. I have a Linksys router configured with PPTP
passthrough enabled along with IPSec and L2TP. There seems to be a problem
between the router and the server. I tested the VPN from a client
workstation and was able to connect to the server so my feeling is that the
RRAS portion is setup properly. I just can't seem to connect from outside
the network. I get an error 800.

Thanks,
Christine
