Internal firewall
If you have a firewall on the internal network, you may need to
adjust its policy to open ports for back-end applications with
which the appliance must communicate. In addition to opening
ports for standard network services such as DNS and email, you
may need to modify your firewall policy before the appliance
can access the following services.
