Ping: Select this to allow the external network to ping the IP Address of the Firewall. This will allow people from the Internet to be able to ping the Firewall. If set to enable, the DFL-80 will respond to echo request packets from the external network. WebUI: Select this to allow the DFL-80 WEBUI to be accessed from the WAN network. This will allow the WebUI to be configured from a user on the Internet. Keep in mind that the DFL-80 always requires a username and password to enter the WebUI. DMZ Interface The Administrator uses the DMZ Interface to set up the DMZ network. The DMZ network consists of server computers such as FTP, SMTP, and HTTP (web). These server computers are put in the DMZ network so they can be isolated from the Internal (LAN) network traffic. Broadcast messages from the Internal network will not cross over to the DMZ network to cause congestions and slow down these servers. This allows the server computers to work efficiently without any slowdowns. IP Address: The private IP address of the Firewall's DMZ interface. This will be the IP address of the DMZ port. The IP address the Administrator chooses will be a private IP address and cannot use the same network as the External or Internal network. NetMask: This will be the netmask of the DMZ network. Ping: Select this to allow the external network to ping the IP Address of the Firewall. This will allow people from the Internet to be able to ping the Firewall. If set to enable, the DFL-80 will respond to echo request packets from the external network. WebUI: Select this to allow the DFL-80 WEBUI to be accessed from the External (WAN) network. This will allow the WebUI to be configured from a user on the Internet. Keep in mind that the DFL-80 always requires a username and password to enter the WebUI. 21
