Point-to-Point Protocol over Ethernet (PPPoE) relies on two widely accepted standards, PPP and Ethernet. PPPoE enables your home network PCs that communicate on an Ethernet network to exchange information with PCs on the Internet. PPPoE supports the protocol layers and authentication widely used in PPP and enables a point-to-point connection to be established in the normally multipoint architecture of Ethernet. A discovery process in PPPoE determines the Ethernet MAC address of the remote device in order to establish a session.
Creation with the Connection Wizard
To create a new PPPoE connection, perform the following steps:
1. Click the New Connection link in the ‘Network Connections’ screen. The ‘Connection Wizard’ screen will appear.
2. Select the Internet Connection radio button and click Next. The ‘Internet Connection’ screen will appear.
Figure 44: Point-to-Point Protocol over Ethernet
4. Enter the username and password provided by your Internet Service Provider (ISP), and click Next. The ‘Connection Summary’ screen will appear.
Figure 45: Connection Summary
5. Check the ‘Edit the Newly Created Connection’ check box if you wish to be routed to the new connection’s configuration screen after clicking Finish. 6. Click Finish to save the settings.
The new PPPoE connection will be added to the network connections list, and will be configurable like any other connection.
General
Schedule By default, the connection will always be active. However, you can configure scheduler rules in order to define time segments during which the connection may be active. Once a scheduler rule(s) is defined, this field changes to a combo box, allowing you to choose between the available rules.
Network Select whether the parameters you are configuring relate to a WAN, LAN or DMZ connection, by selecting the connection type from the combo-box.
MTU MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for Internet transmission. The default setting, Manual, allows you to enter the largest packet size that will be transmitted. The recommended size, is 1492. You should leave this value in the 1200 to 1500 range.
To have the gateway select the best MTU for your Internet connection, select Automatic.
Underlying Connection Specify the underlying connection above which the protocol will be initiated.

Internet Protocol
Select one of the following Internet Protocol options from the ‘Internet Protocol’ drop down menu:
• Obtain an IP Address Automatically • Use the Following IP Address
Please note that according to the selection you make in the ‘Internet Protocol’ drop down menu, the screen will refresh and display relevant configuration settings.
Obtain an IP Address Automatically Your PPP connection is configured by default to obtain an IP automatically. You should change this configuration in case your service provider requires it.
The server that assigns the gateway with an IP address, also assigns a subnet mask. You can override the dynamically assigned subnet mask by selecting the ‘Override Subnet Mask’ and specifying your own mask instead.
Figure 47: Internet Protocol Settings – Automatic IP
Use the Following IP Address Your WAN connection can be configured using a permanent (static) IP address. Your service provider should provide you with this IP address, subnet mask and the default gateway IP address.

DNS Server
Domain Name System (DNS) is the method by which website or domain names are translated into IP addresses. You can configure the connection to automatically obtain a DNS server address, or specify such an address manually, according to the information provided by your ISP.
To configure the connection to automatically obtain a DNS server address, select ‘Obtain DNS Server Address Automatically’ from the ‘DNS Server’ drop down menu.
Figure 49: Automatic DNS Settings
To manually configure DNS server addresses, select ‘Use the Following DNS Server Addresses’ from the ‘DNS Server’ drop down menu. Specify up to two different DNS server address, one primary, another secondary.

Routing
You can choose to setup your gateway to use static or dynamic routing. Dynamic routing automatically adjusts how packets travel on the network, whereas static routing specifies a fixed routing path to neighboring destinations.
Routing Mode Select one of the following routing modes:
Route Use route mode if you want your gateway to function as a router between two networks.
NAPT Network Address and Port Translation (NAPT) refers to network address translation involving the mapping of port numbers, allowing multiple machines to share a single IP address. Use NAPT if your LAN encompasses multiple devices, a topology that necessitates port
translation in addition to address translation.
Device Metric The device metric is a value used by the gateway to determine whether one route is superior to another, considering parameters such as bandwidth, delay, and more.
Default Route Select this check box to define this device as a the default route.
Multicast - IGMP Proxy Internal IGMP proxy enables the system to issue IGMP host messages on behalf of hosts that the system discovered through standard IGMP interfaces. IGMP proxy enables the routing of multicast packets according to the IGMP requests of LAN devices asking to join multicast groups. Select the ‘Multicast IGMP Proxy Internal’ check-box to enable this feature.
Routing Table Allows you to add or modify routes when this device is active. Use the ‘New Route’ button to add a route or edit existing routes.

Internet Connection Firewall
Your gateway’s firewall helps protect your computer by preventing unauthorized users from gaining access to it through a network such as the Internet. The firewall can be activated per network connection.
To enable the firewall on this network connection, select the ‘Enabled’ check box.
