Hi,

Actually, you need either public IP or DDNS domain to reach the FortiGate from outside as the user will not be aware of how to reach the FortiGate if the public IP is not known.

thanks your reply. 

 

Yeah without ip public it is not simple. I though with protocol like l2tp or sstp i will be able to make (client to site vpn i've sstp server on my office). Thanks again for your time.

My suggestion is to set up a dial-up IPsec VPN. Let the site without (permanent) public IP dial out to the FGT. Using a VPN is the only safe way to access a FGT for management.

No way, sorry. I imagined that you have a Fortigate externally. Just a FC will not do.

If you have access to the ISP router, you could port forward something onto the FGT WAN port. But if you don't I don't see any way to achieve this.

By the same token, we always use SSL VPN for remote FGT access.

Hey Stoller,

for IPSec or SSLVPN to FortiGate, you will need a public IP or hostname to connect to, if FortiGate should be receiving the connection attempt.

In your case, you would need to set up something on your ISP router (where the actual internet breakout is) to forward connections to a specific port/IP/hostname through to FortiGate, but you mentioned this is not an option, correct?

If you  have a different VPN server (with a public IP), FortiGate could initiate a connection to it (as a spoke, essentially), and you could reach FortiGate through that other VPN server.

But:
- either, you must make FortiGate reachable from internet somehow (DDNS, port forwarding)

- or FortiGate must establish a connection to a different VPN gateway to which you can also connect, and reach FortiGate through that
