=Basic 3G Config=
If you have an AAISP data SIM, the FireBrick can be configured to use this as a backup connection, by using a 3G dongle plugged into the USB port. Any routed legacy IPv4 blocks will continue to work across this link, but so far IPv6 isn't supported (without using a tunnel).
ProvidedThe youexample usebelow your AAISP username and password, then that'sis all you need to get the dongle configured and up. If your main broadband connection goes down, the FireBrick will automatically switch to use the 3G connection, then back again once your main connection is back.

=Config with Tunneled IPv6 Fallback=
If using AAISP, then the options for IPv6 routing on the [[:Category:Control Pages|Control Pages]] allow an IPv6 block to be routed to a tunnel endpoint if the main routing (i.e. ADSL/FTTC) goes down. This means IPv6 can be routed to the 3G dongle if the main broadband(s) go down. The MTU will be limited though. For more configuration options see [[FireBrick 2700 Configuration]].
 
 
 
=3G profiles - turningTurning the dongle off outside of office hours=
Sometimes we don't want the dongle to be online 24x7 and want it turned off outside of office hours.
This example brings the dongle online for quick fallback during office hours, and leaves it powered up but disconnected.
