PPTP VPN Fortigate 110c

Dear experts,

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?

first enable PPTP.. try to enable PPTP from CLI mode
just add a group before selecting the previous option.
select ip mode
then ip address range ...means starting and ending range.
then user group for obtaining ip address for authenticated user

then starting ip and ending ip

local ip/reserved ip for pptp client----means you need to reserve some lan ip for remote client
and also select the pptp user group from the list.


some times you may find that , there is no front end/web based option for pptp vpn.it depends on forti os version.
don't worry enable the same from cli mode..it will work
