Windows Server 2003 and RRAS Firewall
How to open ports on Windows Server 2003 with Routing and Remote Access (RRAS) enabledIf you intuitively try to use the Windows Firewall applet in Control Panel, you will be greeted with the error message:
"Windows Firewall cannot start because another program or service is running
that might use the network address translation component (Ipnat.sys)"
This is because RRAS replaces the built in Windows Firewall with its own basic firewall. The solution is to find the firewall settings built into RRAS:
Open RRAS: "Administrative Tools->Routing and Remote Access"
Expand "[your_server_name]->IP Routing->NAT/Basic Firewall"
Right click on the connection you want to configure and select "Properties"
Use the "Services and Ports" tab to configure the RRAS firewall.
In my case I needed to open port 25 for incoming SMTP mail delivery to an Exchange Server. I had a hard time finding these settings.
If you use SBS 2003 with SQL Server 2005 in standard configuration then it listens on port 1433.
You can use BCM with this standard SQL Server configuration also.
To do so, change the port in Outlook BCM (client) to the standard sql server port 1433 entering the following connection string in the server field:
\,1433
If you don't have any named instances then simply type
,1433
Usually there a no changes for the RRAS firewall required and it works in peaceful coherence.
