and mentioned tools
Microsoft has a pair of test tools pptpsrv and pptpclnt, to test for GRE pass-through, which are available as part of the Windows resource kit or from:;displaylang=en&familyid=49ae8576-9bb9-4126-9761-ba8011fabf38&displaylang=en

Log onto the client or VPN server machine and connect to the other with remote desktop, or a similar remote management tool. At a command line on the client machine, run pptpclnt and on the server run pptpsrv. The client machine will send a set of GRE packets to the server and it should show as received if GRE is able to pass. The server is then supposed to respond and the client indicate received, but I have never had that part work. The one direction client to server is usually enough to test.

Following links outline the use of the test tools:
