P-870H/HW Series User's Guide
PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up
connection. It allows your ISP to use their existing network
configuration with newer broadband technologies such as ADSL.
The PPPoE driver on your device is transparent to the computers
on the LAN, which see only Ethernet and are not aware of PPPoE
thus saving you from having to manage PPPoE clients on individual
computers.
PPPoE dial on demand
IP alias allows you to partition a physical network into logical
networks over the same Ethernet interface. Your device supports
three logical LAN interfaces via its single physical Ethernet
interface with the your device itself as the gateway for each LAN
network.
Your device's packet filtering function allows added network
security and management.
