9.4 PPP Interfaces

Use PPPoE/PPTP interfaces to connect to your ISP. This way, you do not have to install or manage
PPPoE/PPTP software on each computer in the network.
Figure 136 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 ZyWALL/USG and only one computer.
Therefore, the subnet mask is always 255.255.255.255. In addition, the ZyWALL/USG always
treats the ISP as a gateway.
