Pfsense: Dualstack IPv6 + IPv4 with DSL over PPPoE


Dualstack IPv6 + IPv4 with DSL over PPPoE

Interfaces -> WAN

  1. IPv4 Configuration Type: PPPoE
  2. IPv6 Configuration Type: DHCP6

DHCP6 Client Configuration

PPPoE Configuration

Interfaces -> Bridge0

Because I have a LAN,WIFI bridge0, so I have to set my static IPv6 IP’s at the bridge0 interface:

Navigate to Services / DHCPv6 Server & RA / bridge0 / Router Advertisements:

Situation: Router Advertisements does not proper work, if there is a bridge configured. Because, pfSense does not configure a link local address on the bridge. See this bug in pfsense. Bug is also included in 2.3.2-RELEASE-p1.

Workaround in /etc/inc/ did not work for me. So this is my workaround (after a pfsense reboot) until it is fixed:

  1. Navigate to Interfaces / Bridge0 Change IPv6 Configuration Type: Track Interface Track IPv6 Interface: IPv6 Interface: WAN IPv6 Prefix ID: 0
  2. Save and apply change. After that, PfSense configures the missing Link Local address to the bridge.
  3. Revert step 1, save and apply.

Now the radvd works proper.
