Here we will build a config file for a FB2700, from scratch, it should help you to build a configuration for your line(s) and help you understand the XML syntax etc.

Overview

We have an ADSL line with the following details:

Username= abc@a.1 Password=secret
Routed IP block = 90.155.1.0/28

Default Config

The default configuration (or a fully-loaded FireBrick) looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<config xmlns="http://firebrick.ltd.uk/xml/fb2700/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://firebrick.ltd.uk/xml/fb2700/
http://firebrick.ltd.uk/xml/fb2700/0.00.605.xsd"
timestamp="1970-01-01T00:00:07Z">
<port name="LAN1" ports="1"/>
<port name="LAN2" ports="2"/>
<port name="LAN3" ports="3"/>
<port name="LAN4" ports="4"/>
<interface port="LAN1">
<subnet comment="dhcp client"/>
<subnet ip="2001:DB8::1/64 10.0.0.1/24" nat="true"
comment="Temporary IPs for setup only, delete when finished configuring"/>
<dhcp ip="10.0.0.100-199"/>
</interface>
<ppp port="LAN4" username="startup_user@startup_domain" password=""
comment="Example PPPoE config for DSL/FTTC/FTTP/etc"/>
<services>
<ntp/>
<telnet comment="Set allow IP list to restrict access"/>
<http/>
</services>
<rule-set target-interface="LAN1" drop="reject" comment="default
firewall rule - block incoming">
<rule source-interface="self" comment="allow from the FireBrick
though"/>
</rule-set>
</config>

Which sets up the 4 Ethernet ports as separate LANs, and an IP of 10.0.0.1 (and 2001:DB8::1) with the FireBrick acting DHCP server on the first port. So, connecting a computer to Port 1 should get you a 10.0.0.x IP address, and you can access http://10.0.0.1

Port 4 is set as an example of a PPPoE client, we'll set this up a little later.

Configuring Initial Basic Settings

Set yourself a user with full debug rights, eg:

<user name="john" timeout="PT20M" level="DEBUG" password="secret"/>

Modify the ntp time server to use the AAISP time server:

<ntp timeserver="90.155.53.32 2001:8B0:0:53::5A9B:3520"/>

modify the telnet service to permit only access from your LAN:

<telnet allow="90.155.1.0/28"/>

LAN Subnet

We want to use just Ethernet port 1 on the FireBrick for our LAN, we'll be connecting port 1 to a switch, and all our devices will be plugged in to that switch.

So, first we'll add a new subnet, this can go under the current 10.0.0.1 subnet (which we'll delete later.) And we'll make this a DHCP server:

<interface name="LAN" port="LAN1">
<subnet ip="90.155.1.1/28" comment="LAN"/>
<dhcp ip="90.155.1.2-12"/>
</interface>

Remove the existing DHCP settings for the 10.0.0.1 interface.

Our config now looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<config xmlns="http://firebrick.ltd.uk/xml/fb2700/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://firebrick.ltd.uk/xml/fb2700/
http://firebrick.ltd.uk/xml/fb2700/0.00.605.xsd" timestamp="1970-01-01T00:00:07Z">
<user name="john" timeout="PT20M" level="DEBUG" password="secret"/>
<port name="LAN1" ports="1"/>
<port name="LAN2" ports="2"/>
<port name="LAN3" ports="3"/>
<port name="LAN4" ports="4"/>
<interface port="LAN1">
<subnet comment="dhcp client"/>
<subnet ip="2001:DB8::1/64 10.0.0.1/24" nat="true"
comment="Temporary IPs for setup only, delete when finished configuring"/>
</interface>
<interface name="LAN" port="LAN1">
<subnet ip="90.155.1.1/28" comment="LAN"/>
<dhcp ip="90.155.1.2-12"/>
</interface>
<ppp port="LAN4" username="startup_user@startup_domain" password=""
comment="Example PPPoE config for DSL/FTTC/FTTP/etc"/>
<services>
<ntp timeserver="90.155.53.32 2001:8B0:0:53::5A9B:3520"/>
<telnet allow="90.155.1.0/28"/>
<http/>
</services>
<rule-set target-interface="LAN1" drop="reject" comment="default
firewall rule - block incoming">
<rule source-interface="self" comment="allow from the FireBrick
though"/>
</rule-set>
</config>

PPPoE

The FireBrick 2700 supports PPPoE - so you can use it to connect via a modem, eg a:

FTTC Modem
A standard issue AAISP ZyXEL P660-D1, in bridge mode
Another modem set for bridge mode
A modem such as a TP-Line or Draytek

Example XML Configuration (now deprecated, as ppp config now in top level)

   <port name="PPPoE" ports="1"/>
   <interface name="PPPoE" port="PPPoE">
      <ppp username="abc@a.1" password="secret" mtu="1492" graph="AAISP ADSL"/>
   </interface>

Herewe are using the first ethernet port as the one connected to the modem... We had also set up the other 3 ports as the LAN. More details in the FireBrick documentation.

Native IPv6

Assuming you have an IPv6 block allocated to your line on Clueless and you're using the FB for PPPoE, then all the FB config needs is:

An IPv6 address on the LAN subnet
ra="true" in the subnet

Your computers should then get IPv6 details. test on http://ip.help.me.uk
