    Configuring Bridging The ADSL Router can be configured to act as a bridging device between your LAN and your ISP. Bridges are devices that enable two or more networks to communicate as if they are two segments of the same physical LAN. This chapter describes how to configure the ADSL Router to operate as a bridge.

  • Page 118: Using The Bridging Feature

    SSABR-B/SSABR-BU ADSL Ethernet Router User’s Guide Bridges vs. Routers: The essential difference between a bridge and a router is that a router uses a higher-level protocol (such as the IP) to determine how to pass data. IP data packets contain IP addresses that specifically identify the destination computer.

  • Page 119: Defining Bridge Interfaces

    SSABR-B/SSABR-BU ADSL Ethernet Router User’s Guide Defining Bridge Interfaces To enable bridging, you simply specify the device interfaces on which you want to bridge data, and then enable bridging mode: 1. Log into Configuration Manager and click the Bridging tab.

  • Page 120: System Mode

    SSABR-B/SSABR-BU ADSL Ethernet Router User’s Guide If you enable bridging on an interface that has already been assigned an IP address, then it is considered IP-enabled and will route (rather than bridge) IP packets received on the interface. The interface will bridge non-IP data it receives, however.
