Need help setting up a VPN on Server 2008 R2

By ditchmagnet ·
I have tried following a guide:

But I am able to create a connection from a client. I am not sure what I am doing wrong.

My router is a DIR-655, and I think I have it configured correctly.

Here is the error the server records when I try to connect:
"The user DOMAIN\administrator connected to port VPN3-127 has been disconnected because no network protocols were successfully negotiated.

Please help, or tell me what other information I should provide.

Under ALG configuration

I have IPSec (VPN) checked, and I also added protocol 4 to the virtual server list (47 is also on the virtual server list). Still not working.

I haven't setup and CA or anything. That was not in any guide I found. Do I need to do that?

I have just put the computer in the DMZ and it still will not work.

What router ports do you have forwarded?

by robo_dev In reply to Under ALG configuration

PPTP Ping Test Tool is useful:

I would assume that the client is not getting far enough to get an IP address?

Make sure personal firewalls are not an issue on server or client.

Ports list and PPTP tool results

by ditchmagnet In reply to What router ports do you ...

The server has a static IP of

All ports listed are forwarded to the server.

PPTP - 1723 (TCP)

L2TP - 1701 (UDP)

GRE - (no ports) Protocol 47

IPSec - 500 (UDP)

GRE? - (no ports) Protocol 4

I will try that PPTP tool next. My router at home allows me to create a VPN connection to my laptop from my netbook. Maybe I will try my home router (wrt54g running DD-WRT) in the dlinks place and see what happens.

I am running the PPTP tool, and it is just stuck at "Listening on PROTOCOL 47 for incoming GRE packets..."
