Apologies but I'm new to P and I'm trying to get my head around this. Here's my setup.

I'm using a FrameWork laptop intel 11 as standalone, so no battery, just the mb. Nic is the 2.5Gbe FW module.
Network setup is Unifi.
The machine IP is not in the DHCP reservation.

here's my etc/network/interfaces
Code: 
auto lo
iface lo inet loopback

auto enx9cbf0d000630
iface enx9cbf0d000630 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.164.1.29/24
        gateway 192.164.1.1
        bridge-ports enx9cbf0d000630
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094

pvecm updatecertsff
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-100

Everything works fine, after an X amount of time, yesterday was after 5 hours, the day before after 7, today it even kept happening every few minutes, the network goes down. Can't access via UI nor SSH.
The system is up, if I'm connected to it I can systemctl restart networking that's the only thing that starts the whole thing again.
I just have two vm one using the untagged vlan, the second usign a tagged vlan.

Am I missing something here? Everything seems to be right from what I was able to see around... not a super (at all) Debian expert so please bear with me! I currently "solved" having a cronjob that restarts the network every X minutes but there's nothing worse than that! :D

Is DHCP lease time by any chance is around the same 5-7 hours you mentioned?
Click to expand...
it's actually 24hrs. The system was stable since a couple of days. Then, I started a fresh new VM to install the system (ubuntu server with iso) and just after I selected 'install ubuntu'. the whole thing was unreachable again... first time in more than 2 days... I don't know what to think....
