MikroTik RouterOS PPPoE Offloading

This example setup for RouterOS 7.22 configures a MikroTik router as a PPPoE offloader. The router establishes a connection to a PPPoE server (e. g. over GPON or DSL), acquires an IPv4 address and an IPv6 prefix and delegates these to a downstream firewall via DHCP. The MikroTik device acts purely as a router, it has no firewall / NAT rules.

This is motivated by wanting a basic IP over Ethernet connection for the WAN interface of the main firewall (e. g. OPNsense). Specific hardware and protocols required for the WAN uplink are handled by the MikroTik device. RouterOS is known to have a robust PPPoE implementation.

It is assumed that the router has no default configuration like bridges, firewall rules etc.:

Icecast protocol specification

What is the Icecast protocol?

When speaking of the Icecast protocol here, actually it's just the HTTP protocol, and this document will explain further how source clients need to send data to Icecast.

HTTP PUT based protocol

Since Icecast version 2.4.0 there is support for the standard HTTP PUT method. The mountpoint to which to send the data is specified by the URL path.
