An issue could potentially occur when clicking Connect to start tunnel mode SSL VPN.
The tunnel will start up for a few seconds, then shut down.
Which of the following statements best describes how to resolve this issue?

A.
This user does not have permission to enable tunnel mode. Make sure that the tunnel mode widget
has been added to that user’s web portal.

B.
This FortiGate unit may have multiple Internet connections. To avoid this problem, use the
appropriate CLI command to bind the SSL VPN connection to the original incoming interface.

C.
Check the SSL adaptor on the host machine. If necessary, uninstall and reinstall the adaptor from
the tunnel mode portal.

D.
Make sure that only Internet Explorer is used. All other browsers are unsupported.
