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!

Using DSL in Home Office and Having Difficulty Accessing Customer Node via VPN

Asked by chipdukes in Miscellaneous Networking, Networking Hardware Firewalls, IPSec Security Protocol

Tags: ,

I run a consulting business out of my home office, where I use BellSouth DSL.  I have approximately 7 customers' networks/servers that I need to access via VPN.  All but one customer use the latest Citrix client to connect to their network.  The problem is that though I can successfully connect to their VPN networks, I cannot access the AS400's on their private networks when I am sitting behind my PIX 501 firewall.  If I plug my laptop directly into the DSL IFITL connection (or even use dial-up), I have no problem accessing the nodes on the customer's private network via VPN, which leads me to believe I am missing some configuration setting(s) on my firewall.

Here is my current running configuration:
