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 8.0.3 site-to-site VPN disconnects remote VPN clients

Asked by rschoebel in Cisco PIX Firewall, Virtual Private Networking (VPN), IPSec Security Protocol

Tags: Cisco, PIX 515, PIX 8.0.3, command line configuration help

I'm trying to establish a site-to-site VPN between a PIX515 image 8.0.3 and a PIX501.

I have configured Cisco VPN client access using the configurationin the snipit window and it works.

However when I try adding the following commands to establish a site-to-site VPN all VPN clients are disconnected. When they try reconnecting they successfully authenticate with IAS, but fail in "securing the communications channel".

crypto ipsec transformset STRONG esp3des espmd5hmac
crypto map outside_map 20 match address JLG_VPN
crypto map outside_map 20 set peer 100.20.20.10
crypto map outside_map 20 set transformset STRONG
>>>>crypto map outside_map interface outside<<<<<<     This line disconnects all VPN clients
isakmp enable outside
isakmp policy 10 authentication preshare
isakmp policy 10 encryption 3des
isakmp policy 10 hash sha
isakmp policy 10 group 5
isakmp policy 10 lifetime 86400

tunnelgroup 100.20.20.10 type ipsecl2l
tunnelgroup 100.20.20.10 ipsecattributes
presharedkey *

Previously another PIX515 running a 6.3 image was successfully used to allow VPN client access as well as a site-to-site VPN link, however the same configuration no longer works. The remote PIX501 consofuration remains unchanged.

The above was taken from cisco Document ID: 67912.
