[. . . ] The difference between the virtual server and the DMZ function is that the virtual server re-directs a particular service/Internet application (e. g. FTP, websites) to a particular LAN client/server, whereas DMZ re-directs all packets (regardless of services) going to your WAN IP address to a particular LAN client/server. Enable DMZ Enable/disable DMZ Public IP Address The IP address of the WAN port or any other Public IP addresses given to you by your ISP Client PC IP Address Fill-in the IP address of a particular host in your LAN that will receive all the packets originally going to the WAN port/Public IP address above. Click <Apply> at the bottom of the screen to save the above configurations. 35 Denial of Service (DoS) The Broadband router's firewall can block common hacker attacks, including Denial of Service, Ping of Death, Port Scan and Sync Flood. If Internet attacks occur the router can log the events. Ping of Death Protections from Ping of Death attack Discard Ping From WAN The router's WAN port will not respond to any Ping requests Port Scan Protects the router from Port Scans. Sync Flood Protects the router from Sync Flood attack. 36 Access You can restrict users from accessing certain Internet applications/services (e. g. Internet websites, email, FTP etc. ), Access Control allows users to define the traffic type permitted in your LAN. You can control which PC client can have access to these services. Deny If you select "Deny" then all clients will be allowed to access Internet accept for the clients in the list below. Allow If you select "Allow" then all clients will be denied to access Internet accept for the PCs in the list below. Filter client PCs by IP Fill in "IP Filtering Table" to filter PC clients by IP. Add PC You can click Add PC to add an access control rule for users by IP addresses. Remove PC If you want to remove some PCs from the "IP Filtering Table", select the PC you want to remove in the table and then click "Delete Selected". If you want to remove all PCs from the table, just click the "Delete All" button. Filter client PC by MAC Check "Enable MAC Filtering" to enable MAC Filtering. 37 Add PC Fill in "Client PC MAC Address" and "Comment" of the PC that is allowed to access the Internet, and then click "Add". If you find any typo before adding it and want to retype again, just click "Reset" and the fields will be cleared. Remove PC If you want to remove some PC from the "MAC Filtering Table", select the PC you want to remove in the table and then click "Delete Selected". If you want to remove all PCs from the table, just click the "Delete All" button. If you want to clear the selection and re-select again, just click "Reset". Click <Apply> at the bottom of the screen to save the above configuration. 38 URL block You can block access to some Web sites from particular PCs by entering a full URL address or just keywords of the Web site. Enable URL Blocking Enable/disable URL Blocking Add URL Keyword Fill in "URL/Keyword" and then click "Add". You can enter the full URL address or the keyword of the web site you want to block. Remove URL Keyword If you want to remove some URL keywords from the "Current URL Blocking Table", select the URL keyword you want to remove in the table and then click "Delete Selected".

Click <Apply> at the bottom of the screen to save the above configurations 39 13 Advanced Settings Network Address Translation (NAT) allows multiple users at your local site to access the Internet through a single Public IP Address or multiple Public IP Addresses. NAT provides Firewall protection from hacker attacks and has the flexibility to allow you to map Private IP Addresses to Public IP Addresses for key services such as Websites and FTP. Select Disable to disable the NAT function. Port Forwarding Port Forwarding allows you to re-direct a particular range of service port numbers (from the Internet/WAN Port) to a particular LAN IP address. It helps you to host servers behind the router NAT firewall. Enable Port Forwarding Enable Port Forwarding Private IP This is the private IP of the server behind the NAT firewall. 40 Type This is the protocol type to be forwarded. You can choose to forward "TCP" or "UDP" packets only, or select "both" to forward both "TCP" and "UDP" packets. Port Range The range of ports to be forward to the private IP. Comment description of this setting. Add Port Forwarding Fill in the "Private IP", "Type", "Port Range" and "Comment" of the setting to be added and then click "Add". Then this Port Forwarding setting will be added into the "Current Port Forwarding Table" below. Remove Port Forwarding If you want to remove a Port Forwarding setting from the "Current Port Forwarding Table", select the Port Forwarding setting that you want to remove in the table and then click "Delete Selected". If you want to remove all Port Forwarding settings from the table, just click "Delete All" button. Click "Reset" will clear your current selections. 41 Virtual Server Use the Virtual Server function when you want different servers/clients in your LAN to handle different service/Internet application type (e. g.
