Request VPN Technique

[Myo_Thu]

Dear all, I have 1 fortigate firewall 100E and 4 fortigates 60E. I want to connect with VPN. I have only one public ip address. I will assign public ip on server behind the 100E and other sites will connect this server through the VPN tunnel. Can connect or not?  What VPN technique should use? Thanks.

Dear Myo Thu, 

Here in this scenario, you can follow Dial Up VPN, in which on the 100E, you just have to configure the DialUp vpn and from the 60E, they all will be establishing the connection with the help of Remote peer ID during the site to site configuration. This ID will be created and shared from the 100E.  (Dialup <-> Site to Site VPN)

After the tunnel establishes, all sites would communicate with the server by using it's private IP address. 

If I'm wrong, please correct me. 

Thanks & regards, 

Viknesh.
