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!

How do I setup the ASA Branch location so clients can receive DNS, IP Helper and Internet from Main Site. Site to Site connectivity has been established. IP pings work fine.

Asked by richxx7 in IPSec Security Protocol, Virtual Private Networking (VPN), Cisco PIX Firewall

Tags: , ,

I currently setup a remote site with the main HQ and successfully configured the VPN tunnel. Traffic is passing through via IP fine. The problem I'm running into is that I need to configure the Clients behind the ASA device to ask for DNS, IP Helper and receive Internet from the HQ site. When I try and resolve a IP to hostname behind the ASA, they just time out. The reason they need internet from the remote site is to be prompted by Websense so theire Internet activity can be tracked. How should I proceed?
