Hi folks,
Need some help please with the "ISA Server detected routes through adapter" warnings...
On a new implementation of a 2 node ISA 2006 array I have multiple internal networks:
10.1.0.0/255.255.240.0 - Network1
10.2.0.0/255.255.240.0 - Network2
10.3.0.0/255.255.240.0 - Network3
172.1.1.0/255.255.255.0 - DMZ
192.168.1.0/255.255.255.0 - Intra-array
1.1.1.0/255.255.255.0 - Internet

I created the network definitions using only the 10.1.0.0 to 10.1.7.255 as I cannot put the 10.255.255.255 in multiple networks which adding the adapter would do...
..but thats where my problem is I believe, in thats what ISA wants??

What have I done wrong, or is this a fundamental design problem?

Can the errors be ignored as it all appears to work, or should I change the configuration, or should I use 172 networks rather than 10 networks (so I can use 172.x.255.255 in the network definitions) ??

Thanks,
Paul
