When you finish making your selections, select Apply.
Specifying a port number for web portal connections
You can optionally specify a different TCP port number for users to access the
web portal login page through the HTTPS link. By default, the port number is
10443 and users can access the web portal login page using the following default
URL:
https://<FortiGate_IP_address>:10443/remote
where <FortiGate_IP_address> is the IP address of the FortiGate interface that
accepts connections from remote users.
1 Go to System > Admin > Settings.
2 In the SSLVPN Login Port field, type an unused port number.
3 Select Apply.
Specifying an IP address range for tunnel-mode clients
The Tunnel IP Range fields on the VPN > SSL > Config page enable you to
reserve a range of IP addresses for remote SSL VPN clients. After the FortiGate
unit authenticates a request for a tunnel-mode connection, the SSL VPN client
connects to the FortiGate unit and is assigned an IP address from this range.
Afterward, the FortiGate unit uses the assigned address to communicate with the
SSL VPN client.
Idle Timeout Type the period of time (in seconds) to control how long
the connection can remain idle before the system forces
the user to log in again. The range is from 10 to 28800
seconds. This setting applies to the SSL VPN session.
The interface does not time out when web application
sessions or tunnels are up. See Setting the idle timeout
setting.
Portal Message If you want to display a custom caption at the top of the
web portal home page, type the message. See Adding a
custom caption to the web portal home page.
Advanced (DNS and WINS Servers) See Adding WINS and DNS services for clients.
DNS Server #1
DNS Server #2
Enter up to two DNS Servers to be provided for the use
of clients.
WINS Server #1
WINS Server #2
Enter up to two WINS Servers to be provided for the use
of clients.
Note: The Tunnel IP Range fields are used to configure tunnel-mode access only. If you
are configuring web-only mode operation, leave 0.0.0.0 values in the Tunnel IP Range
fields. If you are configuring tunnel-mode operation, see “Specifying an IP address range
for tunnel-mode clients” on page 38. For information about enabling certificate-based
authentication through the Server Certificate and Require Client Certificate options, refer to
the FortiGate Certificate Management User Guide.
Note: Do not select port number 443 for user access to the web portal login page. Port
number 443 is reserved to support administrative connections to the FortiGate unit through
the web-based manager.

Caution: Take care to prevent overlapping IP addresses. Do not assign IP addresses that
are already in use on the private network. As a precaution, consider assigning IP
addresses from a network that is not commonly used (for example, 10.254.254.0/24).
