Communication Applications

Select an Application	This lists applications which may generate incoming connections, where the destination (on your local LAN) is unknown.
Send incoming calls to	This lists the PCs on your LAN. If necessary, you can add PCs manually, using the "PC Database" option on the main menu. For each application listed above, you can choose a destination PC. There is no need to "Save" after each change; you can set the destination PC for each application, then "Save".

Multi-DMZ

Overview	DMZ 1 If you have only 1 WAN IP address, only DMZ 1 can be used. The "DMZ" PC will receive all "Unknown" connections and data. This feature is normally used with applications which do not usually work when behind a Firewall. If an Internet application does not work, try using the "Special Applications" feature. If it still does not work, then the DMZ feature should be used. DMZ 2 ~ 7 If your ISP has allocated you multiple WAN IP addresses, you can bind each one to a PC. All incoming connections and data sent to the WAN IP address will be forwarded to the specified PC. All outgoing connections and data from the PC will be given the specified WAN IP address (rather than the default WAN IP address used by DMZ 1.) All WAN IP addresses use the same Network Mask and Gateway, as specified for the default WAN IP address.
Enable	Use this to enable each DMZ entry as required. The DMZ PC is effectively outside the Firewall, making it more vunerable to attacks. For this reason, you should only enable the DMZ feature when required. If Enabled, you must select the PC to be used as the "DMZ" PC. For DMZ 2 to 7, you must also specify the WAN IP address, as explained below.
WAN IP address	DMZ 1 uses the default WAN IP address, so no input is required. If known, the current WAN IP address is displayed. The WAN IP address is unknown if using a dynamic IP address, and no Internet connection exists. DMZ 2 to 7 can only be used if your ISP has allocated additional (fixed) IP addresses to you. Enter the IP addresses allocated by your ISP.
PC	For each DMZ which is enabled, you must select a PC in the list. If the PC uses a fixed IP address, and is not in the list, you can add it using the "PC Database" option on the Advanced Menu.

Special Applications

Special Applications

Special Applications are any Internet applications which cannot work through the built-in firewall. If an Internet application does not work correctly, you can define it as a "Special Application". Click the "Configure Special Applications" button to open the "Special Applications" screen. Only one (1) user can use a Special Application at any time. If the application still does not work, try using the "DMZ" feature.

URL Filter

URL Filter

This feature allows you to block access to Web sites by defining "filter strings". If the "filter string" appears in a requested URL, the request is blocked. Enabling this also affects the Internet "Access Log". If enabled, the "Destination" field in the log will display the URL. Otherwise, it will display the IP Address. Click the "Configure URL Filter" button to enter or change the "filter strings".
