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.

How do I configure the Optional interface to route internet traffic to my web server

Asked by SergeMis in Watchguard Firewall

Tags: , , ,

I have a WatchGuard 750E running Fireware Pro v9.1 (routed mode).  I would like to use an optional interface to route traffic to my webserver on the optional network (DMZ). I have 2 External interfaces (a T1 and DSL) setup for failover.  External IPs say T1 - 199.227.140.5/30 and DSL - 209.12.60.2/29.  I have asked for another IP from my T1 provider and received 97.65.40.90/29.  

How do I route traffic to the new public IP, and then to my webserver on the Optional Interface? I understand at least one 1:1 NAT is necessary from the Public IP to the Optional but I am not sure how to do this.  Also not sure how/where to assign the new public IP (Would it be as a secondary network on the External int. or is it set on the optional?)

My trusted interface has an IP 192.168.1.1 and the trusted network is on 192.168.1.0/24 subnet.  I have given the optional interface an IP of 192.168.2.1 and the web server directly connected to the optional interface an IP of 192.168.2.2

I have configured a policy to allow any traffic from Trusted to the Optional and only allow MS SQL Server and DNS from the Optional to the Trusted. This is working although I might tighten it up the security by specifying the webserver IP in the policy.

I have tried adding the second public IP 97.65.40.90/29 as a secondary on the external interface but Fireware tells me it is not valid.  From the manual it seems I would need an xp on the same subnet as 99.227.140.5/30.  When I try 99.227.140.7/30 it still says its invalid.

Any help would be greatly appreciated,
