DESCRIPTION

Bridge Interface

 

This field is only available when you select PPPoE LLC or PPPoE VC-Muxin 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.

 

 

 

Connection Setting

 

 

 

Connection

Select Always On (Recommended) when you want your connection up all the

 

 

time. The ZyXEL Device will try to bring up the connection automatically if it is

 

 

disconnected.

 

 

Select Connect On-Demandwhen you don't want the connection up all the time

 

 

and specify an idle time-out in minutes. The default setting is 0 minute, which

 

 

means the Internet session will not timeout.

 

 

Select Connect Manually to establish the connection only when you need it.

 

Note: Do not specify an always-on connection unless your

 

telephone company offers flat-rate service or you need a

 

constant connection and the cost is of no concern.

 

 

TCP MSS Option

The TCP Maximum Segment Size (MSS) defines the size of the largest packet

 

allowed on an interface or connection. Enter the TCP MSS in this field. In general,

 

the TCP MSS is 1452.

 

 

IP Address

 

 

 

Get IP Address

Select the type of IP address provided by your ISP. A static IP address is a fixed IP

 

that your ISP gives you. A dynamic IP address is not fixed; the ISP assigns you a

 

different one each time you connect to the Internet.

 

 

Static IP Address

Type your ISP assigned IP address in the field.

 

 

IP Subnet Mask

Enter a subnet mask in dotted decimal notation.

 

 

Gateway

Specify a gateway IP address (supplied by your ISP).

 

 

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.
