PPPoA (RFC 2364)
Some DSL-based service providers use Point-to-Point Protocol over ATM (PPPoA) to
establish Internet connections. If you are connected to the Internet through a DSL
line, check with your service provider to see if they use PPPoA. If they do, you will
have to enable PPPoA.
Complete the following steps to use the PPPoA option.
1 Navigate to the ADSL screen.
Path: Setup > ADSL
2 Select PPPoA from the Connection Type drop-down menu.
3 Enter the Basic Settings values in the following fields:
 Gateway Probing—This feature provides the capability for the residential
gateway to detect if a loss of IP connectivity occurs. Select Enable if you want
the WAG310G to probe the WAN default gateway at certain intervals
(specified by the user) by sending an ARP request and it will look for an ARP
reply from the server. Once a loss in IP connectivity is detected (i.e., no ARP
reply received), the WAG310G will initiate a request for a new DHCP lease.
– Probing Using Unicast—Select Enable to send unicast ARP requests to
the server. Select Disable to send out broadcast ARP.
– Probing Interval—Enter the number of seconds to wait after detecting
the loss of connectivity before probing sending an ARP request.
 Primary (Required) and Secondary (Optional) DNS—Enter the DNS
(Domain Name System) server IP address(es) provided by your service
provider. At least one is required.
 Username and Password—Enter the Username and Password provided by
your service provider.
