Hi Furqoni,

if you can effort two ISA servers, it is the best configuration you can get
;-)

Thanks for your advice Stefaan.  After I read those documents, I think I'll
be use back-to back scenario. Because we need :
- Web publish on DMZ
- portal publish on DMZ
- Terminal services (+Citrix) publish on DMZ
which those servers need access to SQL server on Internla Area (for update
link everyday).
Do you think is it right choice ?
TIA
regards,
Furqoni

Hi Furqoni,

check out

A DMZ interface in a tri-homed scenario is an External interface and should
not be contained in the LAT. So you can NOT publish a server sitting in the
DMZ zone of a tri-homed scenario.

Stefaan

Hi all,
I have problem with ISA 3 homed-server (One to Internal, other to DMZ and
External).  
Before, when I was installed just with 2 NIC (internal and external), User
from external can reach my publish web. But, when I tried to installed NIC#3
also place publish web on DMZ, User from external can't access eventhough
for ping ...then I should disable-enabled the NIC#3 everytime to solve this
(intermitten).
Should I put NIC #3 (interface to DMZ) for Incoming web request ?
Can anybody help out with this ? Any kind of information on how to solve
intermitten problem using 3 NIC Card would be helpful.
I am using Basic authentication on the ISA server.

Thanks
Furqoni
