Hello,
I need to link a server between a domain and a dmz with SQL Server 2005 SP2.
I opened the port 1433 between the dmz and the domain, it's not running.
Do you have an experience about this issue ?
Which port i need to open between the dmz and the domain ?
Thx for advance for reply.

Hi,
Port 1433 will be blocked. If a machine is in a dmz there's a good reason for it - not using the default port adds to the security. Before you do anything, talk to whoever has responsibilty for security in your organisation. They should have a procedure for allowing access from the domain to the dmz. I'd also make sure I had some change control documentation signed off before I did anything too - if things aren't configured properly you're giving the outside world an open door to your domain..
Cheers,
Cath

Yes we got a security team for this, but they do not know the port are needed to link a server between two SQL servers.
It seems that only 1433 TCP is not sufficient.
So i need to know the list for the port to be opened and which direction between them.

You need to talk to whoever is responsible for the dmz, they'll know the enabled ports and anything else you might need to know in order to connect. Procedures around security should be documented somewhere, but probably not many people have access to them - maybe your web/infrastructure guys?
