Interfacing Firebrick to MikroTik RB SXT LTE 4G device
Weaver:
I’m trying to work out how to configure my Firebrick FB2900 to a Mikrotik 4G device. I can of course get some help from AA about this but they are going to say, sorry don’t speak Mikrotik. Various problems:
* I’m used to setting up FB config for PPPoE devices, but I haven’t any experience with other types of interface
* Mikrotik config :no: ??
* This is to be used as a failover device only. A Firebrick supports 3G USB ‘dongle’-type devices with automagical failover; it just works - and with trivial config. Doing failover with any other type of device will entail complex FB config, although AA may be able to help me with this. I have some ideas.Meritez gave me this device last year but due to grave illness of my wife and relatively minor more recent illness of myself we haven’t yet been able to test the device. I have the following docs and resources
* Mikrotik docs:
https://mikrotik.com/product/RBSXTLTE3-7
https://help.mikrotik.com/docs/display/ROS/LTE
* FB2900 docs https://download.firebrick.co.uk/manuals-plain.php?PRODUCT=2900
* AA support website Mikrotik config web page: https://support.aa.net.uk/Router_-_RouterOS_and_Routerboard
* Mikrotik setup video https://www.youtube.com/watch?v=-KNo1B7K-YYRegarding Firebrick failover behaviour, this is something that AA will be able to help me with. I have an idea though; use Firebrick ‘profiles’ - these are predicates / tests / if-conditional config attrib attributes. You define a named predicate or ‘profile’ and mark certain config elements with an XML attribute that reads <some_element profile=‘profile_name’/> and that makes the element become active if the predicate becomes true. A very clumsy way of doing failover would be to define a predicate that is true if all of the lines are down, done by ANDing several individual predicates. I have done something vaguely like this before and I can get help as needed.
I next need to understand the architecture of the Mikrotik network interface, so some reading to do.
Burakkucat gave me some tips concerning minimal tests to see if I have coverage and tests that the SXT works.
I have an AA SIM that I can steal from my 3G USB NIC, or I could order another one for convenience.

Hi Weaver,
I cannot help with the FB configuration, but to access the Tik, I would recommend https://itunes.apple.com/app/id1323064830 on your iPad.
The above app should allow you to connect to the Tik via Mac Address, if it's plugged into your local network.
Weaver:
Wow, thanks. I can use that to test, immediately.

Hi Weaver, have you been able to access the Tik?
Weaver:
My wife and I have still been too ill, although we’re improving. I have to pick a day when she’s not too ill and not too busy. Played her the video the other day so now she ‘gets it’.
