Description

The lack of available options in dhcp6c prevents pfSense from being used with certain ISPs.

For example, Orange France require three options to be sent that are not currently supported in dhcp6c.

I have now issued a PR upstream at hrs-allbsd/wide-dhcpv6 that allows the use of the Keyword RAW as an option. Here is an example of a part of the config file when using the RAW options.

  1. User class "+FSVDSL_livebox.Internet.softathome.Livebox3";
    send raw-option 15 00:2b:46:53:56:44:53:4c:5f:6c:69:76:65:62:6f:78:2e:49:6e:74:65:72:6e:65:74:2e:73:6f:66:74:61:74:68:6f:6d:65:2e:6c:69:76:65:62:6f:78:33;
  2. Vendor class "sagem"
    send raw-option 16 00:00:04:0e:00:05:73:61:67:65:6d;
  3. Authentication
    send raw-option 11 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:65:78:61:6d:70:6c:65;
  4. IA-PD
    send ia-pd 0;
  5. Requests : authentication, domain-name, domain-name-servers;
    send raw-option 6 00:0b:00:11:00:17:00:18;

Several users have been using the modified version of dhcp6c for several months with no issues, but obliviously it would be better if the version of dhcp6c that ships with pfSense supported this 'out of the box'.

Sorry, that's not looking at what I have written... the keyword is raw-option in the config, not RAW.

The improvement request https://redmine.pfsense.org/issues/8173 is essential for IPv6 authentication for Orange (France, UK, Spain, ...),
this method of authentication via DHCPv6 this generalizes to European ISPs. For IPv4, the problem is solved by upgrading https://redmine.pfsense.org/issues/7425.
For your information, this is not a problem for Opensense https://docs.opnsense.org/manual/how-tos/orange_fr_fttp.html / https://github.com/opnsense/dhcp6c.
We have no problem, on solutions PaloAlto, Fortinet, ....

To summarize Pfsense allows authentication with IPv4 but not with IPv6, it's really a pity ☹ ☹ ☹

Thanks for the helps.

best regards,

fred

Is there any workaround for this? I'm experiencing problems because this isn't implemented - with Orange in FR. I've seen some reports that others have installed the opnsense version on their devices, but I haven't been able to find anything concrete. All advice appreciated.

Please let us have these features added to pfSense. Half of france is using OPNsense because nothing happens on this issue with pfSense.
I'm running with a patched dhcpv6 to resolve this issue, but that can't be right i 2022

I have added a PR with the changes of the dhcp6 client : https://github.com/pfsense/FreeBSD-ports/pull/1181
Until the changes are reviewed / applied, you can look my github if you want the dhcp6 client compiled and learn how to make it by yourself for FreeBSD 12.2 armv7 : https://github.com/Superpaul209/dhcp6c-armv7

You can also look this repo https://ftp.yrzr.tk/opnsense/ to download dhcp6c for aarch64.

I hope pfsense devs will update this client asap because we really need those features...
