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 establish a L2L IPSec VPN Tunnel with a Cisco ASA 5505 behind a Netopia 3347 Router via DSL

Asked by ChattNet in Networking Hardware Firewalls, Computer Modems

Tags: Cisco, Adaptive Security Appliance, ASA 5505

I cannot get a Cisco ASA 5505 to establish a L2L IPSec tunnel with a Cisco VPN Concentrator (which is correctly configured). I have new DSL service with Static IPs and an ISP provided Netopia 3347 Router. I have 5 static IPs assigned by the ISP of which I am using the first for the Outside Interface and the Last for the Gateway/DSL LAN Static. I have followed Netopias instructions at www.netopia.com/support/hardware/technotes/CQG_042.html with no luck. See configuration below. I have also attached the output from the ASA showing it's attempts to establish the tunnel. I have a feeling that I am missing something in the pppoe configuration on the ASA?? I have verified ppp authentication as CHAP. FYI: I am using the command line to configure the ASA, not the ASDM.
