SQL Monitor 3

How do I access SQL Monitor through a firewall?

If you are unable to view the SQL Monitor web page, and your browser displays a "cannot connect" type message, then you may need to check that SQL Monitor is not being blocked by the firewall on the web server machine.

If possible, install the Base Monitor on a server that does not need to go through a firewall to access the SQL Servers you want to monitor. If your network configuration prevents this, then we recommend that you use a VPN link between the Base Monitor and the monitored SQL Servers.

If your organization uses Network Address Translation (NAT), then you may not be able to monitor SQL Servers that are subject to it.

To allow access to SQL Monitor through the firewall, follow the steps below.

Allow access to TCP ports and WMI
