Configure FortiGates networking

To configure FortiGates networking:

1. Log into both FortiGate instances. See the instructions in this document for single FortiGate deployment for instructions on initial login, licensing, and post-deployment steps.
2. Go to Network > Static routes.
3. Add a static route to 0.0.0.0/0 via the port1 interface. Specify the first address in the external subnet as the gateway address. Ignore the warning that the gateway IP address may be unreachable.

   

4. Add a static route to internal subnet via port2. Specify the first address in the internal subnet as the gateway address. Ignore the gateway reachability warning.
5. Add static routes to networks 35.191.0.0/16 and 130.211.0.0/22 via port2 with the first address of the internal subnet as the gateway address.
6. In Network > Interfaces, open port1 and port2 and change the Addressing mode from DHCP to Manual. The proper IP address and netmask are autopopulated.
7. In Network > Interfaces, open port3 and enable administrative (HTTPS and SSH) access.
