The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

PPTP VPN: Protocol 47 GRE not coming through to server

Asked by ni68ana in Virtual Private Networking (VPN), Miscellaneous Networking

Hi,
I have a client running Windows XP who wants his computer setup as a VPN server. I did this by creating a new incoming PPTP connection, however when trying to connect to the server from a client (I've tried several), it always gets stuck at "verifying user name and password" and comes back with error 721.
I've installed windows xp support tools and run pptpsrv / pptpclnt to test the connection. When I run the test, port 1723 goes through fine (test message received OK on the server), but no GRE packets are received on the server.
The Siemens SL2-141 router is configured to forward ports 1723 and 47 to the server's internal address. Disabled the router's firewall temporarily but still no go.
I've also opened the relevant ports on the server's windows firewall, and have tried disabling it completely, along with the avast antivirus which is installed.
Where else could the GRE protocol be blocked?
Many thanks in advance.
