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-Band RIP2-M.

 

 

Direction

Use this field to control how much routing information the ZyXEL Device 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 ZyXEL Device 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.

 

Use this field to alter the MAC address so that the PVCs on the ZyXEL Device

 

can establish connections to the network.
