[. . . ] When enabled, the SMC7301TA will provide an IP address, network mask, gateway address (SMC7301TA's private IP address), and DNS addresses to any workstations on the local area network that are configured as a DHCP client. Devices on your network that are configured with public IP addresses are not DHCP clients. Therefore, you need to assign their IP addresses, network mask, default gateway IP address, primary and secondary DNS IP addresses manually. IP Address Assignment-High & Low: the maximum and minimum private IP address which can assigned to each client PC or workstation in the LAN. Step 3: Click Routing, Address Translation or Static DHCP if it is necessary to set these configurati ons. Otherwise click Apply to confirm the configuration and return to the main configuration screen. The IP Routing Table The IP Routing Table contains all the information that the SMC7301TA needs to route an IP data packet. You can view the IP Routi ng Table by 31 clicking on the Routing button at the bottom of the Advanced Internet Access Setup screen (described in the previous section). The following screen shows an example of the IP Routing Table. When an IP packet arrives in the SMC7301TA, IP tries to determine if the destination IP address contained in the packet is within the network defined by the "Dest IP" and "Netmask" pair of an entry in the routing tab le. If a match is found, the packet is forwarded to the interface or profile specified in the "IfName" field. The "Hops" field is the number of routers the packet must travel through in order to reach its final destination. If this value is zero, the destination is in a network directly attached to this router, such as a LAN. If no match is found with a destination network, then a special entry called the "Default IP Route" is used. This normally is set to a path where another router can be reached that has additional information about other networks not known to the Broadband Router, such as the interface to the Internet. If no match is found and a default IP route is not defined, the IP packet is discarded and will go nowhere. This "Static Route" is indicated by an "S" in the Flag's field. Other flag field entries are "H" for host, and "G" for gateway. Note: To delete a static route, select it in the routing table and click the Delete button. 32 Follow the steps to add or to change the default route or add a static route: Step 1: Click the Add button in the IP Routing Table screen to display the following screen: Step 2: Enter the following information: Default Route: select if you want to specify a new default route. Note that the Remote IP Address and Remote IP netmask fields do not appear if you select this option. CAUTION: Misconfiguring the default route may result in abnormal system behavior and/or unnecessary telephone charges. Step 3 Click APPLY. IP Address Translation Configuration 33 For security and economic purposes, the SMC7301TA supports Single User Account feature (SUA). Multiple users in the LAN can share a public IP address from an ISP, and the whole LAN will be viewed as a big "device" by Internet users. [. . . ] All saved configuration changes are restored after the system re -initializes. How to Change the Broadband Router Manager Password After you start using the SMC7301TA, you should change the factory default password.
