7. Click on the Transparent Range list box and click on the Create new address object
option. The management software displays the Add Address Object dialog box.
8. Fill out the fields as detailed in the next three sections to create the three different types of
address objects. The three examples use a subnetwork of 67.115.118.0.
Creating a Transparent Mode PortShield Interface with a Host Address Object
To assign the Host Address Object 67.115.118.90 to portshield1, perform the following steps:
9. Type the name portshield1 in the Name field to identify the address object.
10. Click the Zone Assignment list box and click the LAN option.
11. Click the Type list box and click the Host option to make the address object apply to a
single IP address. Note the Host option is the default option in the list box.
12. Type your IP address, in this example, 67.115.118.90,in the IP Address field. The
management software assumes a subnetwork mask of 255.255.255.255 (67.115.118.90/
32). Note that because of this assumption, the software does not display a field for a
subnetwork mask. Also, the field does not allow you to type enough a /32 notation as part
of the address.
13. Click OK. The General tab of the Port Shield dialog box is displayed.
14. Click the Switch Ports tab. The Switch Ports tab is displayed.
15. Click on P5 in the Available Ports list and click the right arrow ( > ) button to move the port
into the Assigned Ports list.
16. Click OK. The Interfaces list displays, along with the new PortShield interface in the list. It
displays the name, zone, IP address, subnetwork mask, IP assignment method, status, and
comment, and link type status information about the address object you created
(portshield1).
Note The IP address is the actual subnetwork address, not the specific address you entered. In
this example, the address is 67.115.118.0 and not 67.115.118.90. This is because in
Transparent mode, the interface appears to users as having the same address as the
gateway. Therefore your explicit address is invisible or transparent to internet users. It lets
you keep assigned IP addresses in the WAN subnet while protecting those hosts with full
SonicWALL firewall protection (including services, etc.).
17. Click on the Switch Ports option in the left navigation pane.
18. In the graphic of the switch, view port number 5 and verify that the port is colored blue.
19. In the switch port list, view the PortShield Interface column for P5 (port 5) and verify that
the interface listed is portshield1.
20. Refine the configuration of the PortShield Interface. For details, refer to the “Refining the
PortShield Interface” on page 167.
