NAT with PP PoE Client
NAT with PPPoE Client is a network protocol that uses Point to Point Protocol over Ether net (PPPoE)
to connect with a remote site using various Remote Access Service products. This protocol is
typically found when using a DSL modem with an ISP requiring a user name and password to log into
the remote server. The ISP may then allow you to obtain an IP address automatically or give you a
specific IP address.
