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!

PIX 506 to 506e VPN - Cannot pass data from internal to internal

Asked by waifurchin in Network Software Firewalls, Enterprise Firewalls

Tags: pix, vpn

I am desperately trying to establish a VPN between two locations using PIX 506 firewalls in a pre-shared key, 3DES, configuration.  In the configuration shown, both units can ping the outside interface of the other, and show crypto ipsec sa and shoe ipsec isakmp sa commands seem to indicate a tunnel is formed, but I cannot pass even a ping from the inside of one to the inside of the other.   Both locations use static IP - one via T-1, the other via DSL.  The routers on both sides are set to act as simple bridges, and all traffic restrictions/internal firewalls are removed from these units.

I have tried to reduce the commands to the bare-bones minimum to make the process easier.

Hopefully this will be something very simple (though very urgent), and I apologize for the length of this post - if there is a better was to attach configs and debug info, please let me know.
