PPPOE

PPPoE (Point-to-Point Protocol over Ethernet or Point to Point Protocol over Ethernet) is a network protocol for encapsulating PPP over Ethernet layer. It is mainly used to provide broadband connection via cable modem and DSL services. This offers the advantages of PPP such as authentication, encryption, and compression maintenance. In essence, it is a protocol that allows to implement an IP layer over a connection between two Ethernet ports, but with the software features of the PPP, which is used to virtually "dial" to another machine within the Ethernet network achieving a "serial" connection to it, with which you can transfer IP packets based on the characteristics of the PPP protocol.

A proxy or proxy server in a computer network is a server (a computer program or system), which serves as an intermediary for resource requests made ​​by a client (A) or another server (C). For example, if a hypothetical machine A to C requests a resource, it will by a request to B, which in turn forward the request to C; thus C will not know that the request originally proceeded A. This strategic location halfway point is often exploited to support a variety of features: access control, traffic logging, prohibit certain types of traffic, improve performance, keep the anonymity cache Cache provide web, etc.; the latter serves to accelerate and improve the user experience through permits that will keep the web, this is because the next time the Web pages are visited no information on the website will be removed if not to information from the cache recovered.
