Table 12 Interface Setup > Internet (Dynamic IP)

LABEL DESCRIPTION

Encapsulation Select the method of multiplexing used by your ISP from the drop-

down list box. Available options are: 1483 Bridged IP LLC, 1483

Bridged IP VC-Mux, 1483 Routed IP LLC(IPoA) and 1483

Routed IP VC-Mux.

Bridge Interface This field is only available when you select 1483 Bridged IP LLC or

1483 Bridged IP VC-Mux in the Encapsulation field.

Use this field to enable or disable the bridge mode. Activate the bridge

mode when your ISP provides you with more than one IP address and

you want the connected computers to get individual IP address from

ISP’s DHCP server directly.

NAT Use this field to enable or disable Network Address Translation (NAT).

Default Route Select Yes to direct traffic not listed in the routing table to the default

gateway.

Select No to drop traffic not listed in the routing table.

TCP MTU Option The Maximum Transmission Unit (MTU) defines the size of the largest

packet allowed on an interface or connection. Enter the MTU in this

field.

Dynamic Route RIP (Routing Information Protocol) allows a router to exchange

routing information with other routers.

Select the RIP version from RIP1, RIP2-B and RIP2-M.

Direction Use this field to control how much routing information the P-660RU-Tx

sends and receives on the subnet.

Select the RIP direction from None, Both, IN Only and OUT Only.

Multicast Multicast packets are sent to a group of computers on the LAN and are

an alternative to unicast packets (packets sent to one computer) and

broadcast packets (packets sent to every computer).

IGMP is a network-layer protocol used to establish membership in a

multicast group. The P-660RU-Tx supports IGMP v1, IGMP v2 and

IGMP v3. Select Disabled to turn off the feature.

MAC Spoofing This field is only available when you select 1483 Bridged IP LLC or

1483 Bridged IP VC-Mux in the Encapsulation field.

Select Enable to alter the MAC address that you entered below so

that the PVCs on the P-660RU-Tx can establish connections to the

network.
