Hi George,
I'm tempted to guess that your DMZ has
public IPs, whilst your LAN has got private ones, in which case you will need to
forward the database ports of your LAN gateway to the private IP database
server? This kind of set up could be quite complicated, especially if
you've never messed with firewalls and such before.
Regards,
J
Hi All,
We're going to set up an extranet environment. One option is to place our
ColdFusion server under DMZ (DeMilitarize Zone) and the database server on the
LAN. We try to test the connection between the CF server and the db server
without open UDP and most of TCP/IP ports. However, the connection always fail
no matter how many tcp/ip ports open. I've tried to put 1839 or 1433 in the
Data Source setting. Does anyone have similar situation? Could someone give me
an idea what's happening?
Here was the error message when I tried to verified the data
source:
Connection
verification failed for data source: Intranet
[]java.sql.SQLException:
[Macromedia][SQLServer JDBC Driver]The requested instance is either invalid or
not running.
The root cause was that: java.sql.SQLException:
[Macromedia][SQLServer JDBC Driver]The requested instance is either invalid or
not running.
Thank you in advanced.
George
