Cannot connect to SBS 2003 via PPTP VPN connection


I cannot connect to SBS 2003 via PPTP VPN connection.  I have set this up before on another SBS 2003 server without any problem.

I think I have opened the correct port on the router and have run the remote setup wizard in the SBS console.

Can someone please help me T.S. this problem?  I am not sure where to start.

Thank you.

Check the application event log for any errors related to Remote Access and post the details.
i would also sujest checking your dhcp and that the service has started corectly. a troble shooting idea could be to try connecting a vpn on the local lan and tell me if it connects. if it does then we know the prblem lies with the router.
What exactly happens on the client when you try to connect?
Are you able to PPTP-VPN directly to the server when on the internal network?

When connecting remotely:
If it gets to "checking username and password" and gets stuck there, it will be the router that is forwarding port 1723, but not the GRE protocol. Not all routers support this. It could be sufficient to make sure you forward port 1723 for both TCP and UDP. That depends on the device you're using.
If the client is not getting to 'veryfying username and password', port 1723 is not being redirected to the server

When the client connection fails, what error number is presented such as 800, 691, 721, etc.

For reference the following is a good link outlining the requirements and set up of the VPN specific to SBS 2003

I enabled the GRE protocol on the router and that did the trick.  Thank you!

BTW, although I can connect fine now, I am getting this error in the event log on the server every time I connect...
IPBOOTP was unable to receive an incoming message on the local interface with IP address The data is the error code.
Any thoughts?  Thank you.
