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!

Checkpoint SecureClient failing to authenticate (gateway not responding)

Asked by dvanaken in Checkpoint Firewall, Virtual Private Networking (VPN), Miscellaneous Networking

Tags: Checkpoint secureclient vpn

I have two XP users on my LAN that can successfully authenticate and access a customer's remote network via Checkpoint SecureClient R60.  I have tried to install the same client software on three other machines and although I can create a site (and get the key back), none of the three can create a tunnel.  I spent quite a bit of time watching packets and there is something that baffles me.  I see packets on the client NIC interface being addressed to the remote system but they never show up on the firewall (Sonicwall) packet captures.  The remote address must be accessed through the def gateway (the sonicwall).  It's as if the CP client is trying to route differently.  Arp and route tables are as expected.  Also, immediately after the packet is sent to the remote address, the client tries to contact 10.10.0.x which is no network I recognize at all.  Again, two clients work fine - same application (although installed a year ago).  AND - if I give my non-working client an external address and set the def gateway to be my ISP's router and bypass the firewall - success.  I have many different VPN clients (Sonicwall, Nortel, Cisco) that work fine this way and have done so for years.  I am least familiar with the Checkpoint products.  Any checkpoint wizards that can help would be much appreciated. Thanks
