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!

Cannot access OWA through Cisco Pix

Asked by g000se in Cisco PIX Firewall, Simple Mail Transfer Protocol (SMTP)

Tags: , , , ,

Hello.

On Saturday 10/27/07, I had updated my Cisco Pix configuration to Restricting SMTP to specific external IP addresses.  I was able to send and receive email through Outlook.  But I cannot access OWA from outside.  So I reverted back to the original settings.

Here is the proposed config from Saturday:

! erase the current access-list
no access-list outside_access_in
! Reapply the initial entries
access-list outside_access_in permit tcp any host 70.143.123.239 eq www
access-list outside_access_in permit tcp any host 70.143.123.241eq www
access-list outside_access_in deny ip any host 70.143.123.242
! allow incoming mail from the two ip ranges
access-list outside_access_in permit tcp 12.153.120.5 255.255.255.248 host MAILSERVER-IP-ADDRESS eq smtp
access-list outside_access_in permit tcp 12.140.5.100 255.255.255.248 host MAILSERVER-IP-ADDRESS eq smtp
! deny all other incoming mail
access-list outside_access_in deny tcp any host MAILSERVER-IP-ADDRESS eq smtp
access-list outside_access_in permit ip any any
! reapply the access-list to the interface
access-group outside_access_in in interface outside

Where would be the OWA entry?  or would it be in the line below?

static (inside,outside) tcp xxxxxx (my note- External IP) smtp xxxxx (my note- Internal IP)  smtp netmask 255.255.255.255 0 0

I also have two smtp servers.  I wonder if I need to make another entry for the second one and similar to the line above.

Thanks.
