The internet works!

After my last update, we had theoretically IPv6 at home. However, then the first issue came up.
We now have 2 providers and we have to keep it that way.
The standard XS4all Fritz!box 7360 could not do Multi-WAN.
I called out to Eric van Uden from AVM and he was absolutely amazing, giving us very useful tips and tricks for our project. Unfortunately, our Fritz!box 7360 was not able to do it. The more expensive Fritz!box 7390 could, but we had a lot of money to spend on the next challenge, so we decided to go for another solution.

The plan now was to use a computer (ASRock ION 330) as a router/firewall with PFsense.
IPv6 support woth PFSense is still in Beta and we couln't get it to work.
My colleague knows one of the developers of PFSense and put us in contact.
We offered a testbed, but in the end, it just took too long.

Finally, the first challenge was solved. We now run OpenWrt Barrier Breaker on the Netgear WNR3500U. OpenWrt has good IPv6 support, does firewalling, Multi-Wan and DHCP-PD works fine as well!

At the moment we have 3 WAN uplinks:
IPv4 UPC
IPv4 XS4all
IPv6 XS4all

The IPv4 traffic is now loadbalanced between 2 providers but we currently have some issues with that.
