Can't connect to Microsoft SQL via OpenVPN

[johnpoz]

So you are trying to connect to a named instance - unless this is the only instance running on the server it would not be on 1433 but a dynamic port.  See the link I posted.

or a named instance that is the only instance running on the computer. (Named instances have special considerations. See Dynamic Ports later in this topic.)

By default, named instances (including SQL Server Express) use dynamic ports. That means that every time that the Database Engine starts, it identifies an available port and uses that port number. If the named instance is the only instance of the Database Engine installed, it will probably use TCP port 1433. If other instances of the Database Engine are installed, it will probably use a different TCP port. Because the port selected might change every time that the Database Engine is started, it is difficult to configure the firewall to enable access to the correct port number. Therefore, if a firewall is used, we recommend reconfiguring the Database Engine to use the same port number every time. This is called a fixed port or a static port. For more information, see Configure a Server to Listen on a Specific TCP Port (SQL Server Configuration Manager****

Hi All,

I've found the error. It was a misconfiguration of the SQL Server. I've now configured the Instance to run on a fixed Port and now everything is working fine. Thanks for your great help  :)

Glad got it sorted..  Curious why it worked on ipsec tunnel?  Unless you were connecting differently?

Don't know why it is working on the IPSec Tunnel but I was connecting the same way than via OpenVPN. Doesn't matter iT#s working now and I'm happy with that  :)
