Re: ISA Server detected routes - Event 14147

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

The routing table on your computer says that address 10.255.255.255
(broadcast address) would go out of the WAN NIC. ISA configuration, however,
does not have 10.255.255.255 associated with the same network (e.g.
external).

I think that in the case of a broadcast address you can usually ignore this
alert, although the best thing to do would be to add 10.255.255.255 to the
network that WAN is assocuated with.

Event Type: Error
Event Source: Microsoft Firewall

Description:
ISA Server detected routes through adapter WAN that do not correlate with
the network
element to which this adapter belongs. For best practice, the address
range
of an ISA
Server network should match the address ranges routable through the
associated network
adapter as defined in the routing table. Otherwise valid packets may be
dropped as spoofed.
(This alert may occur momentarily when you create a remote site network.
You
may safely ignore
this message if it does not reoccur.)
The address ranges in conflict are: 10.255.255.255-10.255.255.255;.
