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:

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...
