Update/Upgrade 2.7.2 --> 2.8.0 using LTE/Cellular modem
-
Hi!
I tried to upgrade 3 units (APU4+Sierra MC7455) and they all went offline after downloading a bunch of pkg and rebooting.
only LTE connection, no traditional WAN.
Is upgrading through LTE/Cellular supported? I saw the mention "Firewalls must be connected to the Internet to update" in the Netgate docs, but it's not stated clearly if it needs ethernet WAN. I did upgrade units using PPPoE WAN and it works fine.
Thanks for your lights!
