SSl VPN behind NAT

[jorbe]

Hi, I have SSL VPN, but behind nat, I can connect it with web portal, but can not access with forticlient. I translaed port 443, is there any other port which I need to translate, for FortiClient to work. 

 this is  the error "unable to establish vpn connection. the vpn server may be unreachable". I have attached file with configuration.. config is very basic.

Do not put the default port 443 as the SSL VPN port.Conflicts may occur.Put some unused port such as 10443.Open that port externally using a port forwarding rule and point it to your fortigate WAN interface IP.
