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!

Asked by sizgiyaev in Checkpoint Firewall, Virtual Private Networking (VPN), Cisco PIX Firewall

Tags: , , , , , ,

Hi
I have Nokia IP 390 an dNGX R65 installed on. Last week i've configured VPN site to site between us and our customer in US , they have CISCO PIX.
VPN configuration:
IKE Phase 1 : AES-256, MD5
IPsec Phase 2 : AES-256, MD5
We are using shared secret for this VPN Community.
Advanced VPN configuration:
IKE Phase 1 : DH group = group 5 (1536 bit)

All configuration the same on other side (on PIX) according customer's IT.

There is three Smartview tracker logs that i see when trying establish the tunnel:

eth3c0 - this the external interface of our box.
The external IP address of our firewall object is configured properly (that might the problem for cleartext through encrypted connection), so that not a problem.

Any idea?
