[. . . ] Then enter your WAN IP address range(s). Computers connected to the WAN port that are not included are inaccessible to users on your LAN. · Add Range To add a range of addresses, such as "199. 2. 23. 50" to "199. 2. 23. 54", enter the starting address in the From Address field and the ending address in the To Address field. An individual IP address should be entered in the From Address field only. Note: Up to 64 address ranges can be entered. Click Update. Once the SonicWALL has been updated, a message confirming the update is displayed at the bottom of the browser window. Routes If you have routers on your Local Area Network, you have to configure the Static Routes section of the SonicWALL. Click Advanced on the left side of the browser window, and then click the Routes tab. The SonicWALL LAN IP Address, LAN Subnet Mask, WAN IP Address and WAN/DMZ Subnet Mask are displayed in the Current Network Settings section. Refer to these settings when configuring your Static Routes. Page 100 SonicWALL Internet Security Appliance User's Guide To add Static Route entries, complete the following instructions: 1. Enter the destination network of the static route in the Dest. The destination network is the IP address subnet of the remote network segment. Note: If the destination network uses IP addresses ranging from "192. 168. 1. 1" to "192. 168. 1. 255", enter "192. 168. 1. 0" in the Dest. Enter the subnet mask of the remote network segment in the Subnet mask field. Enter the IP address of your router in the Gateway field. This IP address should be in the same subnet as the SonicWALL. If your router is located on the SonicWALL LAN, the Gateway address should be in the same subnet as the SonicWALL LAN IP Address. Select the port on the SonicWALL that the router is connected to either the LAN, the WAN, or the DMZ, from the Link list. Once the SonicWALL has been updated, a message confirming the update is displayed at the bottom of the Web browser window. Restart the SonicWALL for the change to take effect. Note: The SonicWALL can support up to 64 static route entries. DMZ Addresses (SonicWALL PRO 100, PRO 200, and PRO 300 Only) The SonicWALL provides security by preventing Internet users from accessing machines on the LAN. This security, however, also prevents users from reaching public servers, such as Web or e-mail servers. The SonicWALL offers a special DMZ ("Demilitarized Zone") port that provides Internet access to network servers. The DMZ sits between the local network and the Internet. Servers on the DMZ are publicly accessible, but they are protected from attacks such as SYN Flood and Ping of Death. If you are configuring the SonicWALL SOHO3 or the SonicWALL TELE3, please go to Chapter 8, Network Access Rules, for information about setting up publicly accessible servers. Using the DMZ is a strongly recommended alternative to placing servers on the WAN port where they are not protected or established Public LAN servers. Advanced Features Page 101 Click Advanced on the left side of the browser window, and then click the DMZ Addresses tab. Servers on the DMZ must have unique, valid IP addresses in the same subnet as the SonicWALL WAN IP Address. Your ISP should be able to provide these IP addresses, as well as information on setting up public servers.
