Nested VPN tunnels

FortiClient (Windows) does not support parallel independent VPN connections to different sites. However, FortiClient (Windows) may still establish VPN connection over existing third-party (for example, AT&T Client) VPN connection (nested tunnels).

SSL VPN connectivity issues

Latency or poor network connectivity can affect the FortiClient SSL VPN connection. To further help avoid timeouts, increase the login timeout on the FortiGate to 180 seconds using the following CLI command:

config vpn ssl settings

set login-timeout 180

end

Microsoft Windows server support

FortiClient (Windows) supports the AV, vulnerability scan, Web Filter, and SSL VPN features for Microsoft Windows servers.

HP Velocity and Application Firewall

When using an HP computer, a conflict between the HP Velocity application and FortiClient Application Firewall can cause a blue screen of death or network issues. If not using HP Velocity, consider uninstalling it.

Split tunnel

In EMS 6.4.1, application-based split tunneling was configured globally and applied to all IPsec or SSL VPN tunnels. In EMS 6.4.2 and later versions, the application-based split tunneling feature was changed to be configured on a per-tunnel basis. Therefore, a global application-based split tunnel configuration made in EMS 6.4.1 will no longer function after upgrading to 7.0.0. You must complete the per-tunnel configuration after upgrade.

This is unrelated to the FortiOS split tunnel feature.
