Ppp Interface Summary - ZyXEL Communications USG40 User Manual

PPPoE/PPTP/L2TP 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/L2TP interfaces and other interfaces.
• You must also configure an ISP account object for the PPPoE/PPTP/L2TP interface to use.
Each ISP account specifies the protocol (PPPoE or PPTP or L2TP), 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/L2TP interface. You should not have to change any network policies.
• You do not set up the subnet mask or gateway.
PPPoE/PPTP/L2TP 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.
