Hi Devrajh
By strange co-incidence I was going to ask a very similar question today.
This is a very common configuration but I would also like to know of
gotcha's or design flaws.
My options for my fully enclosed system (i.e. no legacy access) are as
follows:
Internet <-> FW1 <-> IIS <-> FW2 <-> SQL
IIS is stand alone. SQL is stand alone.
Using only port 80 and 443 on FW1. User logs into IIS over HTTPS. The
credentials are validated against a user database in SQL 7, when validated
the IIS serves ASP pages pulling data from SQL server. Therefore FW2 is
configured to allow traffic only between IIS and SQL through port 1433. We
will be using ADO on IIS to access Stored Procedures in SQL.
Question #1: Does ADO work fine over port 1433?
Question #2: How is the ADO connection made between IIS and SQL (i.e. where
is the IIS password for SQL stored securely)
Second option is if the solution requires some bespoke COM object
development. These objects will be hosted in MTS and accessed from IIS using
DCOM. A scenario such as:
Internet <-> FW1 <-> IIS <-> FW2 <-> MTS <-> SQL
MTS and SQL can be in their own domain if required.
FW1 is the same. FW2 is configured to allow traffice only between IIS and
MTS. This will be DCOM. MTS to SQL is done using ADO.
Question #3: What ports are required on FW2?
$64000 Question: What would the panel recommend.
Regards
Andrew

----------------------------------------------------------------------------
I have the following setup on three different machines as follows:
1.IIS 4.0 (SP5) Web server on one box as configured Standalone (not in any
domain)in the DMZ segment.
2.MTS server and SQL server 7.0 (SP1)running on a two different boxes other
than the IIS box on the same LAN segment and are part of a NT domain.
3.There is PIX firewall between the IIS server and the MTS/SQL servers.
4.The IIS application uses a DCOM component to access the SQL dB via the
MTS.
Q1 - Facing problems setting up DCOM configuration across firewall and with
the IIS and MTS not a part of the same domain.
Q2 - Facing Performance issues as well.
Can any body help me on this?
