DESCRIPTION
This field is only available when you select PPPoE LLC or PPPoE 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.
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-Demand when 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.
allowed on an interface or connection. Enter the TCP MSS in this field. In general,
the TCP MSS is 1452.
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.
Enter a subnet mask in dotted decimal notation.
Specify a gateway IP address (supplied by your ISP).
Use this field to enable or disable Network Address Translation (NAT).
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.
allowed on an interface or connection. Enter the MTU in this field.
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.
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 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.
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.
