Example static route to an external destination
Figure 24 shows a FortiGate unit that requires routes to the FDN located on the
external network. The Fortigate unit does not require routes to the DNS servers or
management computer because they are located on the internal network.
To connect to the FDN, you typically enter a single default route to the external
network. However, for additional security, you can enter static routes to a specific
FortiResponse server in addition to a default route to the external network. If the static
route becomes unavailable (for example, because the IP address of the
FortiResponse server changes) the FortiGate unit can still receive antivirus and NIDS
updates from the FDN using the default route.
