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 AMG1001-T/AMG1011-T 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.
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.
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.
Type your ISP assigned IP address in the field.
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.
The Maximum Transmission Unit (MTU) defines the size of the largest packet 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 AMG1001-T/AMG1011-T 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
AMG1001-T/AMG1011-T 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.
Select Enable to alter the MAC address that you entered below so that the PVCs on the
AMG1001-T/AMG1011-T can establish connections to the network.
