I have a Turris Omnia with the 3G/LTE kit. We use the Omnia when we travel, to make an easy connection to whatever network we can use and use 3G/LTE as fallback when there is no cabled or wifi network available.
It works quite good, but the only thing I miss at this time, is for the Omnia to use the “cheapest” connection available for all traffic and use LTE/3G only when cabled and wifi are not connected/available.
Currently I manually enable/disable the LTE/3G interface, to prevent it being used. That works fine, but only if the used cabled/wifi connection doesn’t drop. If that happens, everything grinds to a halt and I have to manually enable LTE/3G.
So my question:
Is there a way (maybe with static routes?) to make Omnia use connections for all traffic in a specific order (1. Cable, 2. Wifi, 3. LTE/3G)?
This seems to happen to some degree already and most traffic is routed through cable/wifi in stead of LTE/3G, when cable/wifi is back up, but there is still traffic going out over LTE/3G, according to the package and MB count.
Hope there is a solution for this?
