The following table describes the labels in this screen.
8.6 The PPP Interfaces Screen
Use PPP interfaces (PPPoE/PPTP interfaces) to connect to your ISP so you do not have to
install or manage PPPoE or PPTP software on each computer in the network.
Figure 135 Example: PPPoE/PPTP Interfaces
PPPoE/PPTP interfaces are similar to other interfaces in some ways. They have an IP address,
subnet mask, and gateway used to make routing decisions; they restrict bandwidth and packet
size; and they can verify the gateway is available. There are two main differences between
PPPoE/PPTP interfaces and other interfaces.
