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 can I remotely connect a cisco VPN tunnel?

Asked by ctrolz in Cisco PIX Firewall, Virtual Private Networking (VPN), Network Routers

Tags: Cisco, Cisco 851 router, 12.4

I have a project that includes 6 sites to connect to my home office. I used a combination of the SDM and CLI to configure an Easy VPN server (cisco 2821) at the home office and Easy VPN remote  (Cisco 851)on the 6 remote sites. These were all configured at the home office and have been shipped to the sites. THe VPN config on the remote sites were configured as network extensions with the xauth credentials saved to the router and the tunnel was set to auto. While testing I can bring up the tunnel with the SDM by using the test tunnel option which then prompts me for an SSH user and then the xauth user id and password. Since I will not have anyway to get to the SDM on the remote sites, I would like to know how I can up these tunnels via ssh on the server or remote side, or if there is a way to truely allow auto.
