After new installation, first we completed the networks configuration. Our network template is Back Firewall since we have PIX along the path of ISA server. Routing schema: From All Networks to External : NAT Inbetween internal networks : ROUTE After create the networks and configure the routing we always get this error in the event viewer. We tried different configuration but no luck. Despite this event log entry though everything seems to be working OK. error entry shows up in each reboot. This may causing confusion in the futurue and will triger lots of false positive alerts. Is anybody know or have any idea what is causing this?
Notes: 192 address is only assigned to external NIC nowherelse There is no site to site VPN settings. This is internal use only.

Great Article Yorgy, Thanks,
Unfortunatly this could not help, since we can not bind any IP range or NIC to ISA's default "External" network. Since this is a backend server, we need to assign 192 private IP to the external NIC. This is what we get:
ISA Server detected routes through the network adapter OB1-OUTSIDE 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: 10.255.255.255-10.255.255.255;. Note that this event may be generated once after you add a route, create a remote site network, or configure Network Load Balancing and may be safely ignored if it does not re-occur.
