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.

• You must also configure an ISP account object for the PPPoE/PPTP interface to use.
Each ISP account specifies the protocol (PPPoE or PPTP), as well as your ISP account information.
If you change ISPs later, you only have to create a new ISP account, not a new PPPoE/PPTP
interface. You should not have to change any network policies.

• You do not set up the subnet mask or gateway.
PPPoE/PPTP interfaces are interfaces between the ISG50 and only one computer. Therefore, the
subnet mask is always 255.255.255.255. In addition, the ISG50 always treats the ISP as a
gateway.

At the time of writing, it is possible to set up the IP address of the gateway (ISP) using CLI
commands but not in the Web Configurator.
