I don't want to spend megabucks on a 5G router and cellular contract just for a backup network, so I'm wondering if I could configure the following
Connect a MikroTik RBD52G-5HacD2HnD-TC (hAP ac²) to my Cloud Series router, and when the Fibre company is doing maintenance start tethering on my Android phone and use the hAP ac² in station mode to route to the internet via the phone.
I know that it won't be possible to do IPv4 port-forwarding, but using an IPv6-over-v4 tunnel I should still be able to get port-forwarding to my mailserver over IPv6
Can anyone let me know if this sounds sane? and is there any reason why it wouldn't work?
TIA Banjo
