on the internal network so that the FortiGate unit on the internal network can receive
push updates:
1 Add a port forwarding virtual IP to the FortiGate NAT device.
2 Add a firewall policy to the FortiGate NAT device that includes the port forwarding
virtual IP.
3 Configure the FortiGate unit on the internal network with an override push IP and port.
Adding a port forwarding virtual IP to the FortiGate NAT device
Use the following procedure to configure a FortiGate NAT device to use port
forwarding to forward push update connections from the FDN to a FortiGate unit on
the internal network.
To configure the FortiGate NAT device
1 Go to Firewall > Virtual IP.
2 Select New.
3 Type a name for the virtual IP.
4 In the External Interface section, select the external interface that the FDN connects

For the example topology, enter 45001.
8 In the Map to IP section, type the IP address of the FortiGate unit on the internal
network.
If the FortiGate unit is operating in NAT/Route mode, enter the IP address of the
external interface.
If the FortiGate unit is operating in Transparent mode, enter the management IP
address.
For the example topology, enter 192.168.1.99.
