FireBrick 2700 Configuration

This page describes editing the XML directly. The Firebrick does have a Web User Interface too. Both can be used to edit the config, as they edit the same underlying XML.

These instructions are mostly applicable to the 2500 too. The difference between the 2700 and the 2500 is that:

• The 2700 has a USB port so supports 3G fallback, the 2500 does not have a USB port.
• The 2700 has faster throughput - 350Mbit/s on the 2700 compared to 100Mbit/s on the 2500.

Factory Default Config

The factory default config of a FireBrick looks like this:

<?xml version="1.0" encoding="UTF-8"?>

Quick Start Config

Here we have an example of the FireBrick using NAT:

<?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/download/FB2701/xml/fb2700/1.36.002.xsd"
        patch="22527">
   <system contact="John Doe" log-panic="fb-support"/>
   <user name="admin" password="secret" timeout="1:00:00"/>
   <log name="default" comment="General logging for web viewing"/>
   <log name="fb-support" comment="Log target for sending logs to FireBrick support team">
      <email to="crashlog@firebrick.ltd.uk" delay="10" comment="Crash logs emailed to FireBrick support team"/>
   </log>
   <services>
      <ntp ntpserver="time.aa.net.uk"/>
      <telnet/>
      <http/>
      <dns resolvers="2001:8b0::2020 2001:8b0::2021 217.169.20.20 217.169.20.21"/>
   </services>
   <port name="LAN" ports="1 2 3"/>
   <port name="WAN" ports="4"/>
   <interface name="LAN" port="LAN" ra-client="false">
      <subnet ip="2001:8b0::1/64 10.0.0.1/24"/>
      <dhcp name="DHCP" ip="10.0.0.2-254" lease="1:00:00"/>
   </interface>
   <interface name="WAN" port="WAN" ra-client="true"/>
   <ppp name="AAISP" port="WAN" username="me@a.1" password="secret" graph="AAISP" log="default" nat="true"/>
   <rule-set name="Firewall: LAN" target-interface="LAN" no-match-action="reject" comment="Default firewall rule for traffic to LAN">
      <rule name="Allow Firebrick" source-interface="self" comment="Allow all from the FireBrick to LAN"/>
   </rule-set>
</config>

and here the FireBrick is NAT free:

      <rule name="Allow Firebrick" source-interface="self" comment="Allow all from the FireBrick to LAN"/>
   </rule-set>
</config>

VoIP

Here we have an example of setting up VoIP on the FireBrick, inbound and outbound calls, inbound URI calls, and outbound URI calls to AAISP:

<voip source-ip4="217.169.11.113" source-ip6="2001:8b0:119c:acf2::1">
   <carrier name="AASIP+441234567890" allow="81.187.30.110-119 90.155.3.0/24 90.155.103.0/24 2001:8b0:0:30::5060:0/112 2001:8b0:5060::/48"
            registrar="voiceless.aa.net.uk" username="+441234567890" password="secret" extn="1000"/>
   <carrier name="URI" to="@domain.name" trust-cli="true" extn="1000"/>
   <telephone name="John" display-name="John" username="John" password="secret" extn="1000" carrier="AASIP+441234567890"/>
   <telephone name="AAISP-Sales" extn="400222" uri="sales@aa.net.uk"/>
   <telephone name="AAISP-Accounts" extn="400666" uri="accounts@aa.net.uk"/>
   <telephone name="AAISP-Support" extn="400999" uri="support@aa.net.uk"/>
</voip>

and here we use Direct Dial In, extn= is removed from <carrier> element and ddi= added to <telephone> element:

<voip source-ip4="217.169.11.113" source-ip6="2001:8b0:119c:acf2::1">
   <carrier name="AASIP+441234567890" allow="81.187.30.110-119 90.155.3.0/24 90.155.103.0/24 2001:8b0:0:30::5060:0/112 2001:8b0:5060::/48"
            registrar="voiceless.aa.net.uk" username="+441234567890" password="secret"/>
   <carrier name="URI" to="@domain.name" trust-cli="true" extn="1000"/>
   <telephone name="John" display-name="John" username="John" password="secret" extn="1000" ddi="+441234567890" carrier="AASIP+441234567890"/>
   <telephone name="AAISP-Sales" extn="400222" uri="sales@aa.net.uk"/>
   <telephone name="AAISP-Accounts" extn="400666" uri="accounts@aa.net.uk"/>
   <telephone name="AAISP-Support" extn="400999" uri="support@aa.net.uk"/>
</voip>

Remote Login

Here we allow limited IPv6 addresses access to Telnet and HTTP, this stops you locking yourself out, in the example below 2001:8b0:119c:acf2::2/64 is used but you will need to use your own IP address instead, it also allows AAISP staff to login:

<telnet allow="2001:8b0:119c:acf2::2/64 2001:8b0::/47" local-only="false"/>
<http allow="2001:8b0:119c:acf2::2/64 2001:8b0::/47" local-only="false"/>

then add a user account for AAISP, don't forgot to change password to something else:

<user name="AAISP" password="secret" timeout="1:00:00"/>

Two Lines with 3G Dongle - Fallover

Ports - LAN is on ports 1 and 2, WAN1 is on port 4, WAN2 is on port 3:

<port name="LAN" ports="1 2"/>
<port name="WAN2" ports="3"/>
<port name="WAN1" ports="4"/>

Interface - LAN interface, with DHCP for IPv4 addresses and RA for IPv6 addresses, assumes PPP session is 1500 MTU, if PPP session is 1492 MTU then change 1472 to 1464 in second ra-mtu= element:

<interface name="LAN" port="LAN" ra-client="false">
<subnet ip="2001:8b0:119c:acf2::1/64 217.169.11.113/29" ra="true" ra-mtu="1412" ra-dns="2001:8b0::2020 2001:8b0::2021" profile="DSL-Down"/>
<subnet ip="2001:8b0:119c:acf2::1/64 217.169.11.113/29" ra="true" ra-mtu="1472" ra-dns="2001:8b0::2020 2001:8b0::2021" profile="DSL-Up"/>
<dhcp name="DHCP" ip="217.169.11.114-118" lease="1:00:00"/>
</interface>

Interface - WAN interfaces, RA client is enabled:

<interface name="WAN1" port="WAN1" ra-client="true"/>
<interface name="WAN2" port="WAN2" ra-client="true"/>

PPP - Connect to both lines, MTU is 1500, timeout is 5 seconds, localpref= gives priority to the highest value:

<ppp name="AAISP1" port="WAN1" username="me@a.1" password="secret" mtu="1500" lcp-rate="1" lcp-timeout="5" localpref="1000" graph="AAISP1" log="default" nat="false"/>
<ppp name="AAISP2" port="WAN2" username="me@a.2" password="secret" mtu="1500" lcp-rate="1" lcp-timeout="5" localpref="100" graph="AAISP2" log="default" nat="false"/>

Dongle - Connect over 3G, localpref= gives this connection the lowest priority:

<usb>
<dongle name="AAISP3" username="me@a.3" password="secret" nat="false" localpref="10" graph="AAISP3" log="default"/>
</usb>

Static Route - Brings up IPv6 default route using IPv4 tunnel when both lines are down or unplugged:

<route ip="::/0" gateway="81.187.81.6" profile="DSL-Down" comment="IPv6 default route using IPv4 tunnel"/>

Profiles - Checks if both lines are up or down:

<profile name="DSL-Down" interval="1" timeout="5" recover="1" ppp="AAISP1 AAISP2" invert="true" comment="DSL is Down"/>
<profile name="DSL-Up" not="DSL-Down" comment="DSL is Up"/>
