Question

Site-to-site IPSec VPN with thirdy party products using private IP address on WAN.

Hi All,

 

   I have a Fortigate and trying do a site-to-site IPSec VPN with a thirdy party equipment.

   This equipment use a private IP address in it's WAN interface (10.x.x.x), delivered by ISP. 

   How can I do to configure this VPN? 

   The option to use dynamic dns doesn't work because the dynamic dns of Fortiguard use the IP of the Wan interface and not the public IP address of my ISP.

   

Regards,

Claudio Rezende

    Do you have a static public IP?

    Can you enable Port Forwardings on the ISPs device or all ports forwarded to the FortiGate?

    @gschmitt,

     

         In side of Fortigate I have static public IP address, but in other side not, and I don't have access to ISP router to forward the traffic to firewall.

     

     

    Regards,

    Claudio

    Go to VPN > IPSec > Tunnels

    Enter a Name and select Custom VPN Tunnel

    IPv4

    Static IP Address

    Enter the IP Address of the other side

    Select the connected interface (usually wan1)

    Preshared Key > Enter the key for dialup

    Select encryption as needed and the local and remote address

     

    On the other side (assuming it's fortigate)

    Copy nearly all settings from above but select Dialup User as Remote Gateway

     

    Make sure policies and routes on both sides are created or add them if needed.
