To add a tunnelled IPv6 block to your FireBrick (2500/2700) and advertise it on your LAN subnet is do the following:▼

The smaller MTU is required due to the IPv6 packets being placed inside IPv4 packets.
Once saved, machines on your LAN should be given IPv6 addresses, and they will use the FireBrick as their IPv6 gateway, which in turn will use the

You may need to allow the tunnel into your FireBrick with a rule such as:
<syntaxhighlight lang="xml">
<rule name="IPv6 tunnel" source-interface="WAN" target-interface="SELF" source-ip="81.187.81.6" protocol="41"/>
▲</syntaxhighlight>

It's also really easy to set up an IPv6 tunnel from http://tunnelbroker.net if you are using a FB2700 on an ISP which doesn't already support IPv6. If the details for your tunnel on your control panel say your server IPv4 address is 192.0.2.26 and your client IPv6 is 2001:DB8:ABCD:123E::2 then you would put the following in your config:
<syntaxhighlight lang="xml">
<route comment="Tunnel server IPv4 address" ip="::/0" gateway="192.0.2.26"/>
<loopback comment="Tunnel client IPv6 address" ip="2001:DB8:ABCD:123E::2"/>
</syntaxhighlight>
Then create a LAN subnet entry with your routed /64 (or /48) and firewall rule as above.
