You'll need to use an ADSL or FTTC modem in bridge mode for this to work - see the page for your modem to see how to set that up. This guide provides an example configuration for Debian Jessie, but it should largely work for future versions. This has been tested with Jessie, Stretch and Buster. = Prerequsites = * a Linux PC with Debian ~~Jessie~~ already installed and two network interfaces - one for the connection to the modem, and one for the connection to your LAN * a ADSL or FTTC modem, or a fibre ONT (for FTTP) (as appropriate for your connection) * '''eth0''' is plugged directly into your modem or ONT * '''eth1''' will be used for your LAN Note that under Buster, you can expect naming conventions for the interfaces to be different, you'll therefore have to pay close attention to updating the interface names as you follow the guide. = Enabling IP forwarding = * '''noauth''' - don't require A&A to send authentication details * '''persist''' - automatically reconnect if the connection drops * '''maxfail 0''' - sets ~~the~~ the number of consecutive failed connection attempts before pppd gives up. Setting this to 0 means that pppd will retry forever * '''mtu 1492''' - sets the max MTU for packets inside the PPP connection - 1492 is a "safe" value for PPPoE on most hardware. Some modems will be able to use "baby jumbo frames" (RFC 4638). See the "Using a full 1500 MTU" section for more details. * '''noaccomp''' - disables address/control compression * '''default-asyncmap''' - disables the ~~negotation~~negotiation of an asyncmap - forces all control characters to be escaped * '''+ipv6''' - enable IPv6 support * '''ipv6cp-use-ipaddr''' - use your IPv4 address as the local identifier for IPv6CP
