Edit for the solution:
I would have never imagined, but chatgpt came up with the solution:
I'm not sure if it's related for the NIC setup, someone with actual networking knowledge should chime in.
My server is an old HP ProLiant DL360 G6, as you can see in the screenshot the NIC is in a shared network port mode, maybe that's the reason?
Hello guys,
I'm in a need of help, since my drives failed in my server and I couldn't get back the data to make it boot.
I remember having a difficult time to configuring VLAN to work, now I have to do it again, sadly I didn't make a backup of the configuration.
The goal is to get PVE (host) to be in VLAN 201 tagged up and running. Here's my configuration:
/etc/network/interfaces
/etc/hosts
/etc/resolv.conf
ip route
brctl show
tcpdump -i enp2s0f0 host not 10.66.0.21
tcpdump -i vmbr0
tcpdump -i vmbr0.201
Router tcpdumps
tcpdump -i eth1
tcpdump -i eth1.0
tcpdump -i eth1.201
I'm not sure if it should behave like my router, but as you can see the vmbr0.201 interface doesn't see traffic. bridge-id x.8002 is vlan 0, and x.8001 is vlan 201 according to tcpdump -i eth1 -e vlan.
My router's configuration could be ruled out, since it was working properly before my SSD's decided to make my life hell.
Whatever I'm trying to ping from Proxmox I get Destination Host Unreachable.
I'm really desperate now, I spent days playing around with multiple /etc/network/interfaces configurations, with no luck. Please help me.
