Figure 5: Edit SSL VPN settings

Enable SSL VPN

Select to enable SSL VPN connections.

Tunnel IP Range

Specify the range of IP addresses reserved for tunnel-
mode SSL VPN clients. Type the starting and ending
address that defines the range of reserved IP
addresses. See

Specifying an IP address range for

tunnel-mode clients

.

Server Certificate

Select the signed server certificate to use for
authentication purposes. If you leave the default setting
(Self-Signed), the FortiGate unit offers its factory
installed (self-signed) certificate from Fortinet to remote
clients when they connect. See

Enabling strong

authentication through security certificates

.

Require Client Certificate

If you want to enable the use of group certificates for
authenticating remote clients, select the option.
Afterward, when the remote client initiates a connection,
the FortiGate unit prompts the client for its client-side
certificate as part of the authentication process.

Encryption Key Algorithm
See

Specifying the cipher suite

for SSL negotiations

.

Select the algorithm for creating a secure SSL
connection between the remote client web browser and
the FortiGate unit.

Default - RC4(128
bits) and higher

If the web browser on the remote client is capable of
matching a 128-bit or greater cipher suite, select this
option.

High - AES(128/256
bits) and 3DES

If the web browser on the remote client is capable of
matching a high level of SSL encryption, select this
option to enable cipher suites that use more than 128
bits to encrypt data.

Low - RC4(64 bits),
DES and higher

If you are not sure which level of SSL encryption the
remote client web browser supports, select this option to
enable a 64-bit or greater cipher suite.
