pfSense with IPv4 and IPv6

I recently persuaded pfSense running on an ALIX based system with a Draytek Vigor 140 ADSL modem to connect up with IPv4 and IPv6 to AAISP. Here are some notes on how.

Hardware

The example ALIX system I have is a bit pricey but it comes with pfSense already installed and three 100Mb interfaces. You can get just the board and do it yourself quite easily for a lot less. Make sure you have some way to access the RS232 based console in some way in case it all goes wrong if you use this box.

A very good alternative is an old PC. Either put several network cards in it or get a switch such as a Netgear 108 and learn about 802.1Q VLANs to make one NIC into several.

You need at least two interfaces, one of LAN and one for WAN

Software

At the time of writing (20 May 2012) you need a development snapshot from the 2.1 series.

Addressing

For IPv6, AAISP supply you with a /48 prefix from which you can create multiple /64 subnets for your use. There are over 65,000 /64 subnets in a /48 each with more addresses than you can eat! Click on the green "add /64" button on your control page to create them.

For IPv4, note down the additional subnet range that you should have been assigned.

Configuration

First off, get IPv4 sorted out. Follow one of the many guides out there.
