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!

Cisco ASA Not passing traffic (possibly static translation problem)

Asked by UptimeSystems in Cisco PIX Firewall, Networking Hardware Firewalls, Network Routers

Tags: Cisco, ASA, 5505, Cisco ASA Not passing traffic (possibly static translation problem)

Background:

Hello.  I'm in the process or replacing our Cisco PIX 501 with a new Cisco ASA 5505.  Behind the firewall are a hanful of servers providing services such as terminal services, exchange, etc.  The old PIX has a handful of static 1-to-1 NAT translations for each server, and an access list opening up ports as necessary to each server.  I've tried to reproduce this config on the ASA.

Problem:

The problem is when I swap our old PIX out with the new ASA (with a matching config as far as I can tell) none of the servers setup with 1-to-1 NAT translations can traverse the ASA to the Internet.  That is--they cannot ping Internet hosts, browse the web--anything.  I CAN however, ping Internet hosts from inside the ASA.  This tells me the problem is with the translation, or possibly the access lists.

I've attached the config as a "code snippet" below.  I've replaced our real public IP addresses with 200.88.88.xxx addresses in the config.  Inside IP addresses have not changed.  As you can see, I've used ip names to make referring to public IP and internal/private IP addresses easier.  For exmple, INT-SERVER1 will be the name I assign to the internal (192.168.111.x) addess of Server1, and EXT-SERVER1 will be the name I assign to its public IP address--the address I do a 1-to-1 translation.

I mostly did this config via commandline, and a few tweaks in the GUI (ASDM).  I'm pretty comfortable with PIX IOS, and have also deployed working ASA's in less complex environments.

Can anyone see an error in my config?  I've scoured it several times looking for an error, but I don't see one.  (Also--while troubleshooting I was sure to clear the ARP cache on the servers, and even restart the network switch that connects the ASA to the servers.  I also CAN ping/telnet into the ASA from the servers--just not pass traffic through them).

Help!  Thanx in advance.
