Hello,
I have ISA2004 setup with three adapters.
First adapter: internal
Second adapter: external
Third adapter: Remote network available through a private Hardware VPN.
ISA Network Relationships.
Internal to external (NAT)
Internal to remote (NAT)
Network Rules allow traffic from the internal to external
Network Rules allow traffic from internal to remote.
If I bring up both interfaces I can not communicate with the external network
at all. I get the following error message in the isa logs.
Description: ISA Server detected routes through adapter "cs.cornell.edu" that
do not correlate with the network element to which this adapter belongs. The
address ranges in conflict are:
128.84.96.0-128.84.99.255;128.84.103.0-128.84.103.127;128.84.223.0-128.84.223
.255;128.84.227.0-128.84.227.255;. Fix the network element and/or the routing
table to make these ranges consistent; they should be in both or in neither.
If you recently created a remote site network, check if the event recurs. If
it does not, you may safely ignore this message.

I have added each of the networks reachable on the other end of the hardware
VPN in the RRAS static routes section. How can I get rid of this conflit.
This setup was working fine for a month and then just stopped.
Thanks
Bill
