Figure 252   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.
