SSL VPN Configuration, LDAP Authentication & Port Forwarding.

Hi Guys,

Have a good day! I'm new in Firewall Configuration and basic understanding, Anybody share to me how to proper configuring SSL VPN, LDAP authentication and Port Forwarding.  I already read some fortigate documentation but still confusing on actual configuring the Firewall. I'm using Fortigate 90D V5.4.0,build1011 (GA).
