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!

Configuring Cisco ASA Firewall to Allow Inbound & Outbound Traffic to Exchange Server

Asked by LouisVuitton in Cisco PIX Firewall

Tags: , , , ,

Internet---DSL Modem---CiscoASA-----DMZ (Exchange Server)
                                            |
                                   Internal LAN

This is my current setup at home and I'm trying to configure my Cisco ASA 5505 so that my Exchange Server can receive and send mail related traffic to external users and internal users.   My Exchange Server is currently sitting on the DMZ vlan with an internal IP address of 10.0.0.2.   I would like the firewall to allow all typical email related services for Exchange.  

Can someone help me with what additional command lines I need to add or modify?
Thanks in advance,
