    Tap on the network button

    Tap on your standby wan

    tap top right to edit

    and you can turn off the connectivity test. 

    tap top right save

    See if this works or not.

    I'd considered that but it's a bit like "fixing" a blowing fuse by replacing it with 12 1/2 gauge fencing wire.  In particular I don't want to disable connectivity testing entirely, I still want it active when the link fails over to the secondary, with maybe a single "is this thing still on?" test once a week or so in case of something like the carrier disabling the SIM would be good.  Disabling the checking entirely means that I'd only find out if there's a problem when the secondary is actually needed, which defeats the point of automated failover.

    So this is probably also a feature request alongside a problem report, the problem is excessive bandwidth usage in the connectivity test, running at around 20MB a day every day, and the feature request is being able to mark a connection as a metered connection as per things like Windows so the system knows not to generate unnecessary traffic on it.

    Do you know if your metered access will count ping to their default first hop gateway as bandwidth usage? 

    If your system is sensitive to 20MB of data per day, I think the best way is just to disable the tests.

    Not sure how their accounting works, but if it's just a basic ping it shouldn't really amount to much so either a ping is being counted as a ton of data, or the Firewalla is sending a ton of data or perhaps sending a half-ton frequently enough that it all adds up - can you provide any details on what it's doing, i.e. how much and how often traffic is generated?  I've disabled connectivity checks and left it for 24 hours and usage is essentially zero, so all the bandwidth usage was the Firewalla doing connectivity checking.

    The situation in this case is that it's not running over a full (expensive) mobile plan which is unnecessary, it's an M2M link that might get used once a year if there's a problem with the fibre primary link.  So instead of paying a monthly fee like a standard mobile plan you pay a small amount once a year based on data usage, which should be close to zero if it wasn't for the apparent 20MB a day of connectivity checks.

    With the tests disabled, is there any checking done at any point that the link still works?  What I'm worried about is that if there is some glitch I won't find out about it until it's time to fail over, at which point the failover won't work.
