Connecting the FortiGate unit to the network(s)
When you have completed the initial configuration, you can connect the FortiGate unit
between your internal network and the Internet.
The following network connections are available on the FortiGate-50A unit:
• Internal for connecting to your internal network,
• External for connecting to the Internet.
• Modem is the interface for connecting an external modem to the FortiGate-50A.
See
“Configuring the Modem interface” on page 35
To connect the FortiGate-50A unit:
1
Connect the Internal interface to the hub or switch connected to your internal network.
2
Connect the External interface to the Internet.
Connect to the public switch or router provided by your Internet Service Provider. If
you are a DSL or cable subscriber, connect the External interface to the internal or
LAN connection of your DSL or cable modem.

Note:
If you change the IP address of the interface you are connecting to, you must connect
through a web browser again using the new address. Browse to https:// followed by the new IP
address of the interface. If the new IP address of the interface is on a different subnet, you may
have to change the IP address of your computer to the same subnet.
Note:
If you use the setup wizard to configure internal server settings, the FortiGate unit adds
port forwarding virtual IPs and firewall policies for each server. For example, for each server
located on the Internal network the FortiGate unit adds an External
->
Internal firewall policy.
