11.4 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 162 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 and only one computer. Therefore, the subnet mask is always 255.255.255.255. In addition, the ZyWALL 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.
