So, about one year after the first announcement, The Belgian DSL provider EDPnet has started a test-group for native ipv6.

Their ipv6 does not work on the standard (by Belgacom issued) Sagem modems.
You will need to place a router behind the Sagem, which bridges PPPoE perfectly through.

I placed a Mikrotik RB1200 firmware version 5.12.

The IPV6 is enabled through DHCPv6 and you are given an /48 or /56 range, depending if you have static or dynamic ip contract.

I will post here how to have a basic setup to get ipv6 working on your MikroTik.

I assume you already have set up PPPoE. If you don’t know how to initially use the router, please read the documentation first.

The configuration example here is done over the MikroTik terminal.

/ipv6 dhcp-client
add disabled=no interface=pppoe-edpnet-v6 pool-name=DSL pool-prefix-length=48

The interface is the PPPoE interface you created to connect.
The pool-prefix-length is depending on what kind of contract you have, dynamic ip’s = 56, static = 48
Now for the lan-side:

/ipv6 address add from-pool=DSL interface=BR-LAN advertise=yes

The pool was defined in the DHCP-Client
the interface is the LAN interface you have.
advertise will make sure the devices on the lan get router advertisement, so they will obtain a IPV6 IP.
Now the firewall settings

/ipv6 firewall filter
add action=accept chain=input comment="Router - Allow IPv6 ICMP Traffic" disabled=no protocol=icmpv6
add action=accept chain=input comment="Router - Accept established connections" connection-state=established \
 disabled=no

add action=reject chain=forward comment="Lan - Drop everything else" connection-state=new disabled=no \
 in-interface=pppoe-edpnet-v6 reject-with=icmp-no-route

If more details are needed how to set up mikrotik for DSL, leave a comment, i’ll try to update this post then to help out.

Note this is an example and will not guarantee to work with everybody.

I’m not responsible if you fail miserably.
