I've Cisco ASA as a front Firewall and ISA 2004 as a back Firewall and
multiple subnets behind/managed by Cisco Catalyst.
I have an question
We've multiple subnets (handled by Cisco Catalyst), ISA Server only
accessible by the computers in the same subnet since the default gateway in
the internal interface not configured (when it's set to use Cisco Catalyst
VLAN interface it's working well, but it's can not configured that way,
right?) So what should I do to have it accessible by the computers in
different subnet? Routing has added (in Cisco Catalyst) to forward a request
to ISA Server to it's VLAN interface but still no luck. The issue solved when
I configure ISA internal interface
subnet mask to Class B (IP is Class C), can I do it this way?If not. why?
