I'm a bit new to the fortinet systems and currently we have a running Fortigate 110c firewall. it works well but my users are complaining about the VPN. They report to me that they constantly get error code "868 port is already open, the connection could not be established". I have no idea of where to look for a solution.
Also i want to create a new and more secure VPN connection with LDAP Authentication. Is this easy to do? If so can anyone tell me please?
