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.

General ISA Questions

Asked by richsys in MS Forefront-ISA, Windows Networking

Tags: , , ,

Hi Experts,

I tried at the weekend to switch over to ISA 2006 from our current ServGate hardware firewall, but unfortunatley failed and had to roll back to the ServGate to keep the business running this week. They say failing to plan is planning to fail, and thats exactly what I did!

Anyway, I have a few general questions all related in some way to ISA 2006 that I hope you can help me with, I'll start with a brief summary of the setup.

Dell Poweredge 1950 / 2 NICs (LAN & WAN) LAN interface has no gateway defined and uses internal DNS. WAN interface has it's Default Gateway set to the real IP of the Zyxel router it is connected to, and there is no DNS defined on this interface. Client for MS Nets, File & Print Sharing, and NetBT are all disabled on the WAN interface. The WAN interface uses one of the live IPs from our range and all the other live IP's have also been assigned to this interface.

Zyxel Router - Supplied and managed by our ISP (Claranet) and as far as I know is configured to pass everything through to it internal interface with no filtering whatsoever.

Windows 2003 SP2 - member server sitting in the LAN.

My questions:

1. Is it necessary to create a rule to allow our internal DNS servers to query external DNS servers.

2. Are current hardware filewall allows me to define the live IP that our Exchange server uses for outbound communication, I can't see how this can be achieved with ISA. For example, currently inbound/outbound traffic to/from the Exchange server uses  IP xxx.xxx.xxx.235, when ISA is being used it appears that inbound comms uses xxx.xxx.xxx.235 but outbound comms come from xxx.xxx.xxx.238.
I think this will cause some mail to be rejected if the recepients mailserver does a reverse DNS.

3. Do I need to install the firewall client on workstations? I know this is a bit of a 'it's up to you' type question, but any examples of why you have had to use the clients in your environments would be appreciated.

4. If not using the Firewall Client, what is the best way to configure IE to use ISA as it's procy, DNS or DHCP?

I really appreciate any help you can give.

Kind regards
