Go to Firewall > Virtual IP.

Select New to add a virtual IP.

Enter a Name for the virtual IP.
The name can contain numbers (0-9), uppercase and lowercase letters (A-Z, a-z), and
the special characters - and _. Other special characters and spaces are not allowed.
4
Select the virtual IP External Interface:
The External Interface is the interface connected to the source network that receives
the packets to be forwarded to the destination network.
5
Make sure Type is set to Static NAT.
6
In the External IP Address field, enter the external IP address to be mapped to an
address on the destination network.
For example, if the virtual IP provides access from the Internet to a web server on a
destination network, the external IP address must be a static IP address obtained from
your ISP for your web server. This address must be a unique address that is not used
by another host and cannot be the same as the IP address of the External Interface
selected in step 4. However, this address must be routed to this interface.
If the IP address of the External interface selected in step
DHCP, you can enter 0.0.0.0 for the External IP Address. The FortiGate unit
substitutes the IP address set for this external interface using PPPoE or DHCP.
