Pppoe Routed Mode (Rfc2516) - SMC Networks EZ Connect SMC70032AE User Manual

PPPoE Routed Mode (RFC2516)

PPPoE (Point-to-Point Protocol over Ethernet) requires a client software program
to be installed on your PC and can therefore limit the number of PCs connected
to the Internet. To avoid the necessity of installing a PPPoE client on your
computer and to allow more PCs to connect at once, the SMC70032AE has a
PPPoE client program installed.
To activate the SMC70032AE as the PPPoE client, you will need to put your
internal network on a separate, private logical network since the SMC70032AE
will be routing traffic from the PPPoE session to the appropriate PC inside your
network. Click on "PPPoE Routed" under the "CONFIG" menu to begin
configuration.
You will need to assign an internal Ethernet port IP address, which will act as the
gateway for the internal network, and then define the subnet mask.
The internal DHCP server function will be automatically enabled once you check
the "Enable NAT" option. Domain Name System information, which allows
domain names like www.smc.com
on to the internal network using the modem as a DNS server for the internal
network by checking the "Enable primary DNS Relay" option. This option is
recommended if you have chosen the "Enable NAT" option in order for the
modem's address to be set as the DNS server IP address.
An example of LAN port settings is listed below.
LAN port:
♦ LAN IP: 192.168.1.1 (Also set as the gateway for the internal network)
♦ Subnet mask: ff:ff:ff:00 (Hexadecimal form of 255.255.255.0)
♦ Check the Enable NAT on the interface option to enable the DHCP server
function
♦
Check the "Enable primary DNS Relay" option to allow DNS (Domain
Name System) information to be passed to computers on the internal
network
The information for the ADSL port must also be entered below the LAN IP and
subnet mask in order to pass information to the Internet. Your service provider
will give you the VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier)
settings as well as the Encapsulation Method. The VPI range is from 0 to 4095
and the VCI range is from 1 to 65535.
Because PPPoE assigns the IP information automatically, there is no need to
enable the DHCP client for the ADSL port or manually enter the IP information.
However, you will need to know whether your service provider uses
authentication and, if so, whether this authentication is done using PAP or CHAP.
Once you have identified the method used by your service provider, click on the
matching option, either No authentication, PAP, or CHAP. If using PAP or CHAP,
you will also need to enter the User ID and password provided by your service
provider.
The one other setting you will need to enter is the LLC header mode (Data
Encapsulation method). Because your service provider governs this setting, they
will need to indicate to you which setting to configure.
