Part 3 IPv6 Configuration on pfSense with Teksavvy ISP DHCPv6 AND Stateless DHCP
Part 3 shows you how to configure DHCPv6 in tandem with the Router Advertisement Daemon so that you can assign IPv6 addresses to your network using a DHCP server and also extra options like DNS server.
I will also show you how to configure what is called Stateless DHCP. All your devices will give themselves an IPv6 address using SLAAC (Stateless Address Autoconfig) but in addition to that, your devices will also now query the DHCPv6 server NOT for an IPv6 address but only for the extra options configured on your DHCPv6 server like DNS servers.
I noticed that there is a bug in pfSense (or it may be by design, though I can not think of a reason why). When you choose “Assisted” in the Router Advertisements tab, pfSense sends out Router Advertisements, with the “Managed Address Configuration” flag set (enabled). For Stateless DHCP, this SHOULD be disabled (not set). So I then show you which files (radvd.conf & services.inc) to modify on your pfSense box, so that the RA Daemon on pfSense sends out Router Advertisements with the “Managed Address Configuration” flag disabled (not set).
Once I do that, the “Assisted” drop down option works as expected (or at least as expected by me, meaning the RA Daemon starts working as Stateless DHCP).
