Figure 272 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.
