PPPoE Manual

Summary
The PPPoE (Point to Point Protocol over Ethernet) protocol provides extensive user management, network
management and accounting benefits to ISPs and network administrators. Currently PPPoE is used mainly by ISPs to
control client connections for xDSL and cable modems as well as plain Ethernet networks. PPPoE is an extension of
the standard Point to Point Protocol (PPP). The difference between them is expressed in transport method: PPPoE
employs Ethernet instead of serial modem connection.
Generally speaking, PPPoE is used to hand out IP addresses to clients based on the username (and workstation, if
desired) authentication as opposed to workstation only authentication, when static IP addresses or DHCP are used. It
is adviced not to use static IP addresses or DHCP on the same interfaces as PPPoE for obvious security reasons.
The PPPoE client and server work over any Ethernet level interface on the router - wireless 802.11 (Aironet, Cisco,
WaveLan, Prism, Atheros), 10/100/1000 Mbit/s Ethernet, RadioLan and EoIP (Ethernet over IP tunnel).

Specifications
• Packages required: ppp
• License required: Level1 (limited to 1 interface) , Level3 (limited to 200 interfaces) , Level4 (limited to 200
interfaces) , Level5 (limited to 500 interfaces) , Level6 (unlimited)
• Submenu level: /interface pppoe-server, /interface pppoe-client
• Standards and Technologies: PPPoE (RFC 2516)
• Hardware usage: PPPoE server may require additional RAM (uses approx. 9KiB (plus extra 10KiB for packet
queue, if data rate limitation is used) for each connection) and CPU power. Maximum of 65535 connections is
supported.To configure MikroTik RouterOS to be an Access Concentrator (PPPoE Server):
• add an address pool for the clients from 10.1.1.62 to 10.1.1.72;
• add ppp profile;
• add ppp secret (username/password);
• add pppoe server itself.
