IPv6 made easy
ADSL vendors are often really bad with IPv6. I do not expect much native IPv6 support from any of them, so I have configured the ADSL modems to be a bridge. Another plain ethernet/wlan router is then used to do the L3 layers and abobe.
For the layer3 thingies, OpenWRT is an easy and free candidate to use for whole range for different hardware, and a real router/firewalls (I use Mikrotik units) are available for around 50 GBP (5 * 100 Mbps ethernet, IPv4/Ipv6, Ospfv3, etc). Gigabit version for about 90 GBP.
Some caveats still exists, I have seen quite many modem vendors who have their units as "bridge", but only bridge IPv4 traffic. Apparently people in their codeland have really hard time of understanding the difference between L2 and L3. One of the baddies are the latest Zyxel P660HN-series ADSL-modems no IPv6 passed in bridge mode. Telewell units work like a charm, i.e. like a real ADSL-bridge.
