What are some of the problems with PPPoE and Home Networking?
PPPoE is based on many of the same principles used by Dial-Up Network connections. It effectively assumes that individual client machines are connecting to the Internet autonomously. Each computer that connects must run its own PPPoE client to gain an IP address from the provider. Some resulting potential problems with Home Networking are as follows: Difficult Local Configuration. Local machines may not be able to network locally using TCP/IP without expensive local hardware and/or software. Each client that connects may get an IP address in a separate subnet. For two computers in separate subnets to communicate a router is required. Security. PPPoE prevents most hardware based firewalls from functioning properly. Those firewalls with PPPoE support typically use PPPoE relay, which simply allows PPPoE packets to pass without significant inspection or blocking. Performance. Performance can be impacted in two ways. First the PPPoE connection adds additional overhead. Overhead is made up o
