Hello,
I have a couple of ISA servers running in "cache mode" (due to not
having 2 NIC, one facing external and the other facing internal). I'm
using "web publishing" to do redirect the request to an internal web
server, my destination set is set to "all destination".
When I typed in my ISA server IP address (External representation at the
DMZ firewall), I get "can not find server or DNS".
What am I missing? Please help! :)
Thanks,
Sunnie

Thanks Tom! I'm making good use of your book "Configuring ISA server
2000" building firewalls for windows 2000.

Hi Sunnie,
If you install in Integrated mode, you will need at least two NICs, of
which one will have a default gateway assigned to it. The interface with
the default gateway assigned will be the de facto external interface.
HTH,
Tom

Hi,
First of all, thanks for your information. Currently the ISA is being
in use for WEB Proxy (Cache), but going forward, the ISA will be used
for web publishing and such. So I have installed ISA in "intergrated
mode", for that specific. That is why I'm thinking I need external
facing NIC on our ISA servers.
Thanks,
Sunnie

If your ISA is installed in cache-only mode then no, you can only have
the internal facing NIC. You must have ISA in firewall or integrated
mode to have an external facing NIC. In addition, you must also have a
way for an ISA in cache-only mode to retrieve content on behalf of your
clients, be it directly from the source or via an upstream server or
server chain.

Hello,
We have a debate going on as to if we need to have external facing NIC
to
setup "ISA Server 2000 Application Layer Filtering Web Proxy in the
Perimeter Network". Currently we only have NIC facing internal net.
Your advice/help is greatly appriciated.
Thanks,
