**Introduction / Getting ready to make the connection**
|
|
-------------------------------------------------------
|
|
|
|
This guide is for SFR/RED France FTTH using DHCPv4 / DHCPv6 to connect.
|
|
|
|
The guide deals with internet connection and phone. Support for TV has not been tested.
|
|
|
|
.. Note::
|
|
Before starting this guide, you should have the MAC address of your SFR/RED Box. In the guide you should replace xx:xx:xx:xx:xx:xx with your SFR/RED Box MAC address.
|
|
|
|
SFR/RED requires that the WAN interface assignment should look similar to this:
|
|
|
|
.. image:: images/SFRRED_assignations.png
|
|
:width: 100%
|
|
|
|
* WAN interface has MAC xx:xx:xx:xx:xx:xx which is the original WAN MAC of the BOX (spoofed),
|
|
* LAN interface has MAC 00:11:22:33:44:55 which is the original MAC of the firewall,
|
|
* DUID is 00:03:00:01:xx:xx:xx:xx:xx:xx it's derived from the original WAN MAC of the BOX (spoofed).
|
|
|
|
**Configuring the WAN Interface**
|
|
---------------------------------
|
|
|
|
Select :menuselection:`Interfaces --> [WAN]`
|
|
|
|
In order to establish the IPv4 and IPv6 connection, SFR/RED requires that the correct parameters are passed for the DHCPv4 and DHCPv6
|
|
requests respectively.
|
|
|
|
Select options:
|
|
|
|
* IPv4 configuration: DHCPv4,
|
|
* IPv6 configuration: DHCPv6.
|
|
|
|
.. image:: images/SFRRED_WAN_configuration_1.png
|
|
:width: 100%
|
|
|
|
**On the DHCPv4 request it is a requirement to pass the following:**
|
|
|
|
.. image:: images/SFRRED_WAN_configuration_2.png
|
|
:width: 100%
|
|
|
|
.. Note::
|
|
It is necessary to specify the following ”Send Options”:
|
|
|
|
* dhcp-class-identifier "neufbox_NB6VAC-FXC"
|
|
|
|
.. Note::
|
|
It is necessary to specify the following ”Request Options”:
|
|
|
|
* subnet-mask, broadcast-address, time-offset, routers, domain-name, domain-name-servers, host-name, ntp-servers, nis-domain, root-path, merit-dump
|
|
|
|
|
|
**On the DHCPv6 request we need to use raw options**
|
|
|
|
.. image:: images/SFRRED_WAN_configuration_3.png
|
|
:width: 100%
|
|
|
|
.. Note::
|
|
It is necessary to specify the following ”Send Options”:
|
|
|
|
* ia-pd 1, raw-option 16 00:00:a0:0c:00:40:6e:65:75:66:62:6f:78:5f:4e:42:36:56:41:43:2d:46:58:43
|
|
|
|
.. Note::
|
|
It is necessary to specify the following ”Request Options”:
|
|
|
|
* domain-name-servers, domain-name
|
|
|
|
.. Note::
|
|
Set Identity Association options to:
|
|
|
|
* Delegate prefix: checked,
|
|
* id-assoc pd ID: 1,
|
|
* Prefix: ::/0.
|
|
|
|
Set Prefix Interface option to:
|
|
|
|
* Prefix Interface: 8.
|
|
|
|
Click ”Save” and then ”Apply”.
|
|
|

|
**Configuring the LAN Interface**
|
|
---------------------------------
|
|
|
|
Interfaces / Parameters
|
|
+++++++++++++++++++++++
|
|
|
|
Select :menuselection:`Interfaces --> Parameters` and set your DUID.
|
|
|
|
.. image:: images/SFRRED_interfaces_parameters.png
|
|
:width: 100%
|
|
|
|
.. Note::
|
|
The DUID is based on the SFR/RED Box MAC address : 00:03:00:01:xx:xx:xx:xx:xx:xx.
|
|
|
|
Click ”Save” and then ”Apply”
|
|
|
|
Interfaces / [LAN]
|
|
++++++++++++++++++
|
|
|
|
Select :menuselection:`Interfaces --> [LAN]` and set IPv4 to “Static IPv4” and IPv6 Configuration Type to
|
|
“Track Interface”.
|
|
|
|
.. image:: images/SFRRED_LAN_configuration_1.png
|
|
:width: 100%
|
|
|
|
|
|
And define the IPv6 Prefix ID to ”0”
|
|
Finally, set the following parameters as shown:
|
|
|
|
* the IPv4 address to the one wanted,
|
|
* the IPv6 interfacet to ”WAN”,
|
|
* the IPv6 Prefix ID to ”0”.
|
|
|
|
|
|

|
|
:width: 100%
|
|
|
|
Click ”Save” and then ”Apply”
|
|
|
|
|
|
|
|
.. Note::
|
|
It is advisable at this point to reboot the system. This will allow you to retrieve an IPv4 address which will be used in next part.
|
|
|
|
**Configuring NGINX to provision the SFR/RED BOX**
|
|
--------------------------------------------------
|
|
|
|
In order to set up the phone, as the SIP parameters (user/password) are not public, we will add the SFR/RED box in our LAN.
|
|
This will allow us to plug our regular phone in the SFR/RED box.
|
|
|
|
.. Note::
|
|
This how-to does not cover installation of NGINX nor the use of SSH / shell commands.
|
|
|
|
First SSH into your OPNSense firewall and create a folder **/srv/sfrredbox**. In this folder, we will add the scripts used to spoof the SFR/RED Box requests.
|
|
|
|
In this directory create a file **index.php**
|
|
|
|
.. code-block:: php
|
|
|
|
$currentFirewall = 'firewall.localdomain.intra';
|
|
// can probably be replaced with
|
|
// $currentFirewall = exec('hostname');
|
|
if (isset($_GET['ip_dhcp'])) {
|
|
// adjust re0 to your WAN interface
|
|
$_GET['ip_dhcp'] = exec('ifconfig re0 | grep \'inet \' | cut -d\' \' -f2');
|
|
// if the ifconfig command does not work, set the external IP manually
|
|
// $_GET['ip_dhcp'] = 'your.external.ip.address';
|
|
}
|
|
$_SERVER['DOCUMENT_URI'] = str_replace('/index.php', '', $_SERVER['DOCUMENT_URI']);
|
|
$parameters = http_build_query($_GET);
|
|
$url = $_SERVER['REQUEST_SCHEME'].'://'.$_SERVER['HTTP_HOST'].'/'.trim($_SERVER['DOCUMENT_URI'], '/?') .'?'.$parameters;
|
|
$ch = curl_init();
|
|
curl_setopt($ch, CURLOPT_URL, $url);
|
|
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
|
|
curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'readHeaderLine');
|
|
$data = curl_exec($ch);
|
|
$data = preg_replace('/<proxy([^>]+)>([^<]+)<\/proxy>/', '<proxy$1>'.$currentFirewall.'</proxy>', $data);
|
|
curl_close($ch);
|
|
header('Content-Length: '.strlen($data));
|
|
header('Content-Type: application/xml');
|
|
echo $data;
|
|
|
|
|
|
.. Warning::
|
|
Code cannot be copied / pasted as-is, you will have to adjust the parameters and make it consistent with your own settings.
|
|
|
|

.. Note::
|
|
NGINX should be serving the page we have created.
|
|
|
|
|
|
**Configuring Siproxd to provision the SFR/RED BOX**
|
|
-----------------------------------------------------
|
|
|
|
To allow phone to work, the easiest way is to set Siproxd on the firewall.
|
|
|
|
Services / Unbound DNS / General
|
|
++++++++++++++++++++++++++++++++
|
|
|
|
Select :menuselection:`Services --> Unbound DNS --> General`
|
|
|
|
Add parameters to let SFR/RED Box discover the SIP proxy:
|
|
|
|
.. image:: images/SFRRED_services_unbound_configuration_1.png
|
|
:width: 100%
|
|
|
|
.. Warning::
|
|
It appears OPNSense will drop support of functionnality of **advanced** parameters so I don't know if it will be possible in future releases
|
|
to define the DNS stuff using:
|
|
|
|
* local-data: "_sip._udp.firewall.localdomain.intra. 180 IN SRV 10 60 5060 firewall.localdomain.intra."
|
|
|
|
Services / Siproxd
|
|
++++++++++++++++++
|
|
|
|
Select :menuselection:`Services --> Siproxd`
|
|
|
|
Define basic parameters:
|
|
|
|
.. image:: images/SFRRED_services_siproxd_configuration_1.png
|
|
:width: 100%
|
|
|
|
Services / Siproxd / Outbound Domains
|
|
+++++++++++++++++++++++++++++++++++++
|
|
|
|
Select :menuselection:`Services --> Siproxd --> Outbound Domains`
|
|
|
|
Create the configuration for outbound domain:
|
|
|
|
.. image:: images/SFRRED_services_siproxd_configuration_2.png
|
|
:width: 100%
|
|
|
|
.. Note::
|
|
The IP address and the port of outbound domain was discovered using an **host** request on the proxy returned by SFR/RED while provisionning the box.
|
|
You will have to check the <proxy></proxy> fields of **voip2.xml**.
|
|
|
|
.. highlights::
|
|
host -t SRV _sip._udp.residential.p-cscf.sfr.net
|
|
|
|
.. Note::
|
|
the host request result gives available SIP servers with the port to use (in my case 5062).
|
|
|
|
.. highlights::
|
|
_sip._udp.residential.p-cscf.sfr.net has SRV record 10 0 5062 mitry.p-cscf.sfr.net.
|
|
_sip._udp.residential.p-cscf.sfr.net has SRV record 10 0 5062 corbas.p-cscf.sfr.net.
|
|
_sip._udp.residential.p-cscf.sfr.net has SRV record 10 0 5062 trappes.p-cscf.sfr.net.
|
|
|
|
|
|
**Configuring NAT to redirect SFR/RED BOX calls to NGINX**
|
|
----------------------------------------------------------
|
|
|
|
To allow correct port forwarding, we will configure OPNSense to affect a **static** IP to the SFR/RED Box and we will create an alias for it.
|
|
|
|
Services / DHCPv4 / [LAN]
|
|
+++++++++++++++++++++++++
|
|
|
|
Select :menuselection:`Services --> DHCPv4 --> [LAN]`
|
|
|
|
Click on `[+]` to add a static mapping:
|
|
|
|
.. image:: images/SFRRED_services_dhcp_lan.png
|
|
:width: 100%
|
|
|
|
Firewall / NAT / Port Forward
|
|
+++++++++++++++++++++++++++++
|
|
|
|
Select :menuselection:`Firewall --> NAT --> Port Forward`
|
|
|
|
Add a new forwarding rule:
|
|
|
|
.. image:: images/SFRRED_lan_port_forwarding.png
|
|
:width: 100%
|
|
|
|
|
|
|
|
.. Note::
|
|
Right now, everything should be ready. Restart the firewall, once ready plug the SFR/RED Box on your LAN and start it.
|
|
You should be able to enjoy IPv4, IPv6 and Phone.
