=3G Fallback=
The 2700 model has a usbUSB port that can be used with a 3G dongle for connectivity and/or fallback. The FireBrick 2500 does not have a USB port. By using a 3G dongle with 1 or more FTTC/ADSL lines from AAISP you'll be able to fall back to using 3G in the case of the FTTC/ADSL going down - this includes routing of your public IPv4 blocks and IPv6 blocks (IPv6 via a tunnel)
 
==Supported Dongles==
Dongles do vary, and drivers may need to be written to support a particular dongle. Contact us if you have one which is not working. The following dongles are known to work on a FireBrick 2700:
*[[Zoom_USB_dongleZoom USB dongle|ZOOM model 4598]] (Available from AAISP)
*Huawei E353 (Three branding)
*Huawei E170 (BT Branding)
 
=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 (iei.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|FireBrick 2700 Configuration]].
==Example Config==
LAN Interface for IPv6 tunnel over 3G dongle (with MTU 1500):
This example brings the dongle online for quick fallback during office hours, and leaves it powered up but disconnected. Fallback still works outside of office hours but takes a few seconds longer to set up.
 
Note that both <usbUSB> and <dongle> elements can be based on profiles. Leaving <usbUSB> active but disabling <dongle> will leave the dongle powered up but disconnected. Disabling <usbUSB> will physically turn off the USB port and therefore also the dongle. Cold starts take a lot longer!

Will reset the usbUSB controller and re-detect everything from scratch:
