Firewall

Configuring virtual IPs

 

 

4Select the virtual IP External Interface from the list.

The external interface is connected to the source network and receives the packets to be forwarded to the destination network. You can select any firewall interface or a VLAN subinterface. You can set the virtual IP external interface to any FortiGate interface. Table 22 on page 217 contains example virtual IP external interface settings and describes the policies to which you can add the resulting virtual IP.

5Select Static NAT.

6Enter the External IP Address that you want to map 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, the external IP address must be routed to the selected interface. The virtual IP address and the external IP address can be on different subnets.

7Enter the Map to IP address to which to map the external IP address. For example, the IP address of a web server on an internal network.

Note: The firewall translates the source address of outbound packets from the host with the

Map to IP address to the virtual IP External IP Address, instead of the firewall external address.

8Select OK.

You can now add the virtual IP to firewall policies.

External Interface

Description

 

 

internal

To map an internal address to a wan1, wan2, DMZ1, or DMZ2 address. If

 

you select internal, the static NAT virtual IP can be added to

 

Internal->WAN1, Internal->WAN2, Internal->DMZ, and

 

Internal->DMZ2 policies.

wan1

To map an Internet address to an internal, DMZ1, or DMZ2 address. If

 

you select wan1, the static NAT virtual IP can be added to

 

WAN1->Internal, WAN1->DMZ1, WAN1->DMZ2, and WAN1->WAN2

 

policies.

To add port forwarding virtual IPs

1Go to Firewall > Virtual IP.

2Select Create New.

3Enter a name for the port forwarding virtual IP.

4Select the virtual IP External Interface from the list.

The external interface is connected to the source network and receives the packets to be forwarded to the destination network.

You can select any firewall interface or a VLAN subinterface.
