I've screwed up with VLANS - no ping, no GUI, no SSH ....Am I doomed to a rebuild ?

[rsk21]

Hi all

I've had Proxmox running nicely for a few months now.

This weekend I attempted a network clean up and moved all my homelab stuff onto a separate Unifi Vlan using 10.0.30.x

I sorted out the bridge and tagging etc no problem so have my VMs (Home Assistant) and CTs ( Docker, Nextcloud, Adguard) all available both the new VLAN and two more existing ones.

Then I screwed up

I applied the same logic to the VE via the ethernet adapter ( I only have one NIC) and now I can't ping, cant see the GUi and can't SSH.

Everything else is working but I can't get into the VE in any way shape or form

I'm starting to panic now, thinking I'm just going to have to rebuild everything having learned a harsh lesson.

Is there a solution at all ? Could I even go and get hold of a monitor and keyboard and get direct access somehow ?

Any advice gratefully received .

Many thanks

Whats stopping you logging in to the console and editing /etc/network/interfaces ?

Sure, add display + keyboard, login as root and then run nano /etc/network/interfaces, nano /etc/resolv.conf and nano /etc/hosts to fix stuff manually.
