For example the customer site is assigned the addresses 192 168 1 0 24 through 192 168 1 1 24 The address 192 168 1 1 24 is also the default gateway for the remote network The above settings remove any routing forwarding intelligence from the MT330A The associated router configuration will set serial interface s0 to accommodate half bridging for the above example interface sO ppp bridge ip address 192 168 1 1 255 255 255 0 Authentication is optional under PPP In a point to point leased line link incom ing customer facilities are usually fixed in nature therefore authentication is gen erally not required Some networking systems do not define network numbers in packets sent out over a network If a packet does not have a specific destination network number a router will assume that the packet is set up for the local segment and will not for ward it to any other sub network However in cases where two devices need to communicate over the wide area bridging can be used to transport non routable protocols 6 703 NTU W 10BASET 3 Configuration The MT330A features configuration capability via hardware DIP switches This section describes all possible DIP switch configurations of the MT330A 3 4 DIP Switch Configurations The MT330A has an internal DIP switch that enables configuration for a wide range of applications The DIP switch is accessed from the underside Figure 2 shows the location of the DIP swit
