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!

How to configure Cisco 800 to accept PPTP VPN connections

Asked by DavidOHaycox in Network Routers, Virtual Private Networking (VPN)

Tags: Cisco Router 800 PPTP VPN

We have a Cisco 877 router which has been happily accepting incoming Cisco VPN client connections for some time. However, we have a remote user with 64-bit Vista who cannot use the Cisco VPN Client software, as it's 32-bit only. So, we want to set up the 877 to accept incoming VPN connections (terminating at the router, not passed through to a server).

Have set up the router as in the sanitised config below, but when connecting from the client PC, the connection fails with the following error in the application log:

The user [username] dialed a connection named [connection name] which has failed. The error code returned on failure is 800.
or
The error code returned on failure is 808.

What configuration needs to be changed to allow the connection to work? It looks as if the connection isn't even making it past the firewall.

Thanks in advance for any assistance.
