Internode IPv6 configuration for pfSense

Configure as below using the GUI.

Enable IPv6 in pfSense:

  • Click "System" then "Advanced"
  • Click the "Networking" tab
  • Tick the "Allow IPv6" option
  • Click "Save" at the bottom

Firstly your WAN interface:

  • Select "Interfaces"
  • Select your "WAN" interface
  • In the "General Configuration" section, set "IPv6 Configuration Type" as "DHCP6"
  • In the "DHCP6 Client Configuration" section, set the following...
  • Options -> Advanced Configuration: untick
  • Use IPv4 connectivity as parent interface: tick
  • Request only an IPv6 prefix: tick
  • DHCPv6 Prefix Delegation size: 56
  • Send IPv6 prefix hint: tick
  • Debug: untick
  • Do not wait for a RA: untick
  • Do not allow PD/Address release: untick
  • Click "Save"

Secondly, the LAN interface:

  • Select "Interfaces"
  • Select your "WAN" interface
  • In the "General Configuration" section, set "IPv6 Configuration Type" as "Track Interface"
  • In the "Track IPv6 Interface" which will have just appeared:
  • Set "IPv6 Interface" as "WAN"
  • "IPv6 Prefix ID" as "0"
  • Click "Save"

Allow pfSense to reload the interfaces and you're done.

According to RFC 4890 you should always allow the following ICMP types:

  • Destination Unreachable
  • Packet Too BIg
  • Time Exceeded
  • Parameter Problem

...and optionally...

  • Echo Request & Echo Response

Validate your configuration at http://test-ipv6.com/ and/or http://ipv6-test.com/

 

Note: Internode do not offer IPv6 on NBN HFC and FTTC products. This is ostensibly due to these products simply being resold TPG.
