[. . . ] On your LAN computers, a default gateway directs all Internet traffic to the LAN port on the RX3141. Your LAN computers know their default gateway either because you assigned it to them when you modified their TCP/IP properties, or because you configured them to receive the information dynamically from a server whenever they access the Internet. (Each of these processes is described in the Quick Start Guide instructions, Part 2. ) On the RX3141 itself, a default gateway is defined to direct all outbound Internet traffic to a router at your ISP. This default gateway is assigned automatically by your ISP whenever the device negotiates an Internet connection. (The process for adding a default route is described in section 7. 2. 2 Adding Static Routes. ) You may need to define static routes if your home setup includes two or more networks or subnets, if you connect to two or more ISP services, or if you connect to a remote corporate LAN. 39 Chapter 7. Configuring Static Routes RX3141 User's Manual 7. 2 Static Route Figure 7. 1. Routing Configuration Page 7. 2. 1 Static Route Configuration Parameters Table 7. 1. Static Route Configuration Parameters The following table defines the available configuration parameters for static routing configuration. Field Destination Address Description Specifies the IP address of the destination computer or an entire destination network. It can also be specified as all zeros to indicate that this route should be used for all destinations for which no other route is defined (this is the route that creates the default gateway). Note that destination IP must be a network ID. The default route uses a destination IP of 0. 0. 0. 0. Refer to Appendix 12 for an explanation of network ID. Indicates which parts of the destination address refer to the network and which parts refer to a computer on the network. Refer to Appendix 12, for an explanation of network masks. The default route uses a 0. 0. 0. 0 for subnet mask. Gateway IP address Available option include AUTO, Eth0 (LAN), Eth1 (WAN), PPPoE:0 (unnumbered), PPPoE:1 (1st PPPoE session), PPPoE:2 (2nd PPPoE session). These options are selectable from the drop-down list. If AUTO is selected, the router will automatically assign an interface to route the packets based on the gateway IP address. Subnet Mask Gateway Interface 40 RX3141 User's Manual Chapter 7. Configuring Static Routes 7. 2. 2 Adding Static Routes Figure 7. 2. Static Route Configuration Follow these instructions to add a static route to the routing table. Open the Static Route configuration page by double clicking the Advanced menu. Static Route 2. Enter static routes information such as destination IP address, destination subnet mask, gateway IP address and the interface in the corresponding fields. [. . . ] If the computer receives the message, it sends messages in reply. To use it, you must know the IP address of the computer with which you are trying to communicate. On Windows-based computers, you can execute a ping command from the Start menu. Click the Start button, and then click Run. [. . . ]
