Diagnosing Network Connectivity Issues

One of your first tests when configuring a new policy should be to determine whether allowed traffic is flowing to your web servers.

• Is there a server policy applied to the web server or servers FortiWeb was installed to protect? If it is operating in Reverse Proxy mode, FortiWeb will not allow any traffic to reach a protected web server unless there is a matching server policy that permits it.
• If your network utilizes secure connections (HTTPS) and there is no traffic flow, is there a problem with your certificate?
• If you run a test attack from a browser aimed at your website, does it show up in the attack log?

To verify, configure FortiWeb to detect the attack, then craft a proof-of-concept that will trigger the attack sensor. For example, to see whether directory traversal attacks are being logged and/or blocked, you could use your web browser to go to:

http://www.example.com/login?user=../../../../

Under normal circumstances, you should see a new attack log entry in the attack log console widget of the system dashboard.
