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!

Running 2 domains behind a single PIX 501

Asked by DRBibens in Enterprise Firewalls, Networking Hardware Firewalls, Cisco PIX Firewall

Tags: , , ,

I have a personal domain running behind a PIX 501 firewall and all is fine.  I want to add a Mac server and assign a different domain name to it call them DOMAIN-1 and DOMAIN-2 respectfully.

I have both wireless and wired clients and shared resources like printers etc.

I am not sure how to modify the PIX configuration.  I believe that this will do it but I would like an expert review before implementation as I am not comfortable in this environment.


I am providing current and proposed configurations for comment.

           Current Configuration:
                   DSL Router
         Outside IP: xx.xx.xx.185
            Inside IP: xx.xx.xx.186
                             |
                             |
            CISCO PIX 501 (DHCP)
            Outside IP:  xx.xx.xx.186
               Inside IP: 192.168.1.1
                            |
                            |
                 Win2K Server
      DNS, WWW, POP, SMTP. RDS
           Outside IP:  xx.xx.xx.187
