You can now add the virtual IP to firewall policies.
To add port forwarding virtual IPs
1
Go to
Firewall > Virtual IP
.
2
Select Create New.
3
Enter a name for the port forwarding virtual IP.
4
Select 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.
5
Select Port Forwarding.
6
Enter the External IP Address that you want to map to an address on the destination
interface.
You can set the external IP address to the IP address of the external interface
selected in step
4
or to any other address.
For example, if the virtual IP provides access from the Internet to a server on your
internal network, the external IP address must be a static IP address obtained from
your ISP for this server. This address must be a unique address that is not used by
another host. However, this address must be routed to the external interface selected
in step
4
. The virtual IP address and the external IP address can be on different
subnets.
7
Enter the External Service Port number for which you want to configure port
forwarding.
The external service port number must match the destination port of the packets to be
forwarded. For example, if the virtual IP provides access from the Internet to a web
server, the external service port number is 80 (the HTTP port).
8
Enter 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.
9
Enter the Map to Port number to be added to packets when they are forwarded.
If you do not want to translate the port, enter the same number as the External Service
Port.

External Interface Description
port1
To map an address on a network connected to the port1 interface to an
address on a network connected to another interface, VLAN
subinterface, or zone. If you select port1, the static NAT virtual IP can be
added to policies for connections from the port1 interface or any zone
containing the port1 interface, to any other interface, VLAN subinterface,
or zone.
port2
To map an address on a network connected to the port2 interface to an
address on a network connected to another interface, VLAN
subinterface, or zone. If you select port2, the static NAT virtual IP can be
added to policies for connections from the port2 interface or any zone
containing the port1 interface, to any other interface, VLAN subinterface,
or zone.
