## AI overview

A follow-up guide explains how to configure a custom Linux router for Orange FTTH with both IPv6 and IPv4. It describes why using two PPPoE sessions no longer works and presents the Funbox-compatible approach using an IPv6 PPPoE session and an IPIP DS-Lite tunnel.

## Source excerpt

Orange FTTH and IPv6 - part two Three years ago I published a guide on how to configure a custom Linux router to work with Orange FTTH setup: The most important part was getting IPv6 working, since it wasn't possible with the "Funbox" router supplied by the carrier. This seem to have been fixed. In past when using "Funbox", and when setting the PPPoE username suffix to "/ipv6" to enable IPv6, the suffix was automatically dropped every ~24h, and reverted to IPv4-only.
