# IPv6 for generic DSL dialup

## Introduction

This short article shows how to setup IPv6 on a standard DSL connection and how to handover the delegated prefix from your provider in your local LAN.

It's compatible and tested for but not limited to:

- Deutsche Telekom

## Step 1 - General Settings

Go to **System › Settings › General** and check that **Prefer IPv4 over IPv6** is not ticked. This value is default so just check if it has been touched.

Also enable **Allow DNS server list to be overridden by DHCP/PPP on WAN** at the bottom, so you get the correct DNS servers if you just use IPv4 ones.

## Step 2 - Allow IPv6

Next go to **Interfaces › Settings** and verify that **Allow IPv6** is enabled.

## Step 3 - Interface Configuration

In **Interfaces › [WAN]** and set **IPv6 Configuration Type** to DHCPv6 and in section **DHCPv6 client configuration** at the bottom tick:

- Request only an IPv6 prefix
- Send IPv6 prefix hint

Set the prefix size to the one your provider delegates, mostly /56 or 64, sometimes /48.

Then change to **Interfaces › [LAN]** and set **IPv6 Configuration Type** to **Track Interface**. At the bottom in section **Track IPv6 Interface** choose **IPv6 Interface** as WAN and for **IPv6 Prefix ID** a value of 0 is perfectly fine.

Hit Apply and disable/enable the NICs of your internal systems. Depending on the system and vendor, also a reboot could be required.

If you experience problems with the 24h disconnect disrupting connectivity, it may help to set **Prevent Release** in section **Interfaces › Settings**.
