Forwarding non-HTTP/HTTPS traffic

FAQ

Why is FortiWeb not forwarding non-HTTP traffic (for example, RDP, FTP) to back-end servers even though set ip-forward is enabled?

The config router setting command allows you to change how FortiWeb handles non-HTTP/HTTPS traffic when it is operating in Reverse Proxy mode.

When the setting ip-forward is enabled, for any non-HTTP/HTTPS traffic with a destination other than a FortiWeb virtual server (for example, a back-end server), FortiWeb acts as a router and forwards it based in its destination address.

However, any non-HTTP/HTTPS traffic destined for a virtual server on the appliance is dropped.

Therefore, if you require clients need to reach a back-end server using FTP or another non-HTTP/HTTPS protocol, ensure the client uses the back-end server's IP address.

For more detailed information about this setting and a configuration that avoids this problem, see the “Router setting” topic in the FortiWeb CLI Reference:

How to forward non-HTTP/HTTPS traffic

If FortiWeb is operating in Reverse Proxy mode, by default, it does not forward non HTTP/HTTPS protocols to protected servers.

However, you can use the following command to enable IP-based forwarding (routing):

config router setting

    set ip-forward {enable | disable}

end
