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!

Cisco PIX 515 - Setting up L2TP VPN for Windows Vista

Asked by rnuno007 in IPSec Security Protocol, Cisco PIX Firewall

Tags: Cisco, PIX, 515

PIX-515E 64 MB RAM, CPU Pentium II 433 MHz
PIX Version 7.2(2)
ASDM Ver: 5.2(2)

At this point we can connect with Cisco VPN Client 5.x, Shrew VPN Client 2.1 (free IPsec Client that we found that supports 64bit OS) and Windows XP SP3 L2TP native client. The only problem is connection from Windows Vista native L2TP client.

The debug log gives me the impression that there's something wrong on the pre-shared key but i double check it and its correct.  I'm starting to think that maybe its a bug from the 7.2(2) software

I guided my setup from here:
http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a00807213a7.shtml

Below its the snip off the relevant part for the L2TP tunnel Ive also attached the debug log from the connection of a Windows Vista.

Any help would be appreciated to figure this out.

Thank you.
