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.

ISA Server 2004 Route Error 14147

Asked by dekkar in MS Internet Security & Accel, Network Software Firewalls, Enterprise Firewalls

Tags: , , ,

Hi Guys.... I just noticed an error on my ISA server that looks like this:

Event Type:      Error
Event Source:      Microsoft Firewall
Event Category:      None
Event ID:      14147
Date:            18/05/2006
Time:            11:03:30 AM
User:            N/A
Computer:      FBRS-ISA
ISA Server detected routes through the network adapter WAN-14.x that do not correlate with the network to which this network adapter belongs. When networks are configured correctly, the IP address ranges included in each array-level network must include all IP addresses that are routable through its network adapters according to their routing tables. Otherwise valid packets may be dropped as spoofed. The following ranges are included in the network's IP address ranges but are not routable through any of the network's adapters: 192.168.30.0-192.168.31.255;


I had a look at my log, and its seems this error has been occuring a fair bit, over all 3 nics (internal, external, DMZ)... Not too sure if I should be worried or not..

The Route table looks like this:

Active Routes:
Network Destination        Netmask          Gateway       Interface  Metric

Default Gateway:      192.168.14.1
===========================================================================
Persistent Routes:
  Network Address          Netmask  Gateway Address  Metric
     192.168.11.0    255.255.255.0     192.168.13.1       1
     192.168.12.0    255.255.255.0     192.168.13.1       1
     192.168.10.0    255.255.255.0     192.168.13.1       1


And I didnt set this up originally, so I dont really have that much knowledge on how it all fits together....

I do know that
192.168.10.x-192.168.13.x is internal
192.168.50.x is DMZ
192.168.14.x is External

Is anyone able to shed some light on it?

Much appreciated...
