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!

asa 5510 configuration

Asked by Hahaciok in Cisco PIX Firewall, Network Routers

Tags: asa 5510, nat

Hi,

First sorry for bad English

We have old Cisco 2600 series router and have purchased ASA 5510. Now I want to replace router with ASA, but cannot... When I test ASA 5510 in test environment, it seems as if everything is fine, but when I connect to a real environment, that's what happens:

1. As you can see from my network diagram, our LAN address range is 172.30.16.0/24, all users go to the Internet through a proxy server (172.30.16.253), my computer goes directly to the Internet. Now  when I connect ASA 5510 to a real environment, when I try to access the web directly nothing happens, I cannot ping website, the dns is not reachable, but proxy server can reach dns server(but very slow), and users can surf the Internet. Log show nothing shows, except, when I turn on skype, log show portmap translation failed for my ip address...

2. Mail server cannot reach DNS server, ping anything and s.o. Packet tracer shows, that packets must go correctly...

I dont understand, what is wrong, because, as I say, in test environment everything is ok, but in real....

Any ideas, how to solve my problem?
