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/Linksys VPN tunnel with multiple MM_SA_SETUPs

Asked by ciooal in IPSec Security Protocol, Network Software Firewalls

Tags: , , ,

I am attempting to setup a VPN Tunnel between a Cisco PIX 515E and a Linksys BEFSX41.  When I first setup the tunnel it came up and worked just fine for several hours.  I have defined the timeouts on the Linksys as 86400 seconds to match the defaults of the PIX.  When I arrived at the office this morning the tunnel was down and a show crypto isakmp sa on the pix returned the following.  In this instance the SOURCE IP and DESTINATION IP for each sa is the same... which I have never seen before.  The PIX has approximately 40 other IKE partners which are all working as one would expect.  I have never seen one sa create so many entries.

    "SOURCE IP"   "DESINATION IP"    MM_SA_SETUP   0           0
    "SOURCE IP"   "DESINATION IP"    MM_SA_SETUP   0           0
    "SOURCE IP"   "DESINATION IP"    MM_SA_SETUP   0           0
    "SOURCE IP"   "DESINATION IP"    MM_SA_SETUP   0           0
    "SOURCE IP"   "DESINATION IP"    MM_SA_SETUP   0           0
    "SOURCE IP"   "DESINATION IP"    MM_SA_SETUP   0           0
