Ten months ago, I left this setup in place. The 4G modem is external, connected via USB. Performance is good enough, and it was supposed to stay like this for a month or two.
Then life happens, and it remained in that position for over ten months, completely unattended. Not a single minute of downtime, apart from a brief power outage a couple of months ago. The various devices connected over Wi-Fi, cameras, smart switches, and so on, did not experience even a single disconnection.
I’m tempted to turn this setup into a permanent one...

not even software updates? 🧐 Nooooo! 😱
@bryan no. even because they're just routing and firewalling, so no need to update them
@stefano
okay… but also … ok?

@bryan those all affect the 6.x and earlier 7.x and all require the router to be somehow exposed. I trust my lan, but I don't trust my lan so I have a management vlan.
This means: the router isn't accessible from the LAN. And I consider accessing a router via WAN a serious security practise so never expose them.
