    Bridging Configuration This chapter shows you how to configure the Bridging options for the DI-300M. Depending on your particular applications, you will need to configure different menus. We will illustrate the configuration for some applications in the following sections. IPX Spoofing The DI-300M comes with several pre-defined call filters designed to prevent certain IPX packets from triggering a call to a Remote Node.

  • Page 98: Bridge Ethernet Setup

    Bridge Ethernet Setup Bridging is used to forward packets of unsupported protocols whose destination is not on the local Ethernet to the WAN. Basically, all non-local packets are bridged to the WAN; however, the DI-300M applies special handling for certain IPX packets to reduce the number of calls, depending on the setting of the “Handle IPX”...
  • Page 99 Handle IPX—Set this parameter to None if there is no IPX traffic on the LAN or if you do not want to apply any special handling for IPX. Set it to Client if there are only client workstations on the LAN. Set to Server if there are only IPX servers on the LAN.

  • Page 100: Lan-To-Lan Application

    LAN-to-LAN Application A typical LAN-to-LAN application is to use the DI-300M to call from one office to another office such that stations on one network have access to stations on the remote side and vice versa. You will need to configure a Remote Node in order to dial out to another office.

    Filter Configuration About Filtering Your DI-300 or DI-300M uses filters to decide whether or not to allow passage of a data packet and/or to make a call over the ISDN line. There are three types of filters involved: incoming data filters, outgoing data filters, and call filters.

  • Page 105: Di-300'S Filter Structure

    For incoming packets, your DI-300 or DI-300M applies data filters only. Packets are processed depending upon whether a match is made. The router allows you to customize the filter sets that you wish to use. This following sections describe how to configure the router’s filter sets.
