[SOLVED] No network, fresh install

[Dergonic]

Hi

I juste setup Proxmox 7.2-1 on a new bench. All went perfect except the network is not working.
Once install done, I cannot reach https://10.10.84.11:8006/. And from proxmox local console, I cannot ping my router on 10.10.84.1

Here is my current config files
/etc/network/interfaces

auto lo
iface lo inet lopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
    address 10.10.84.11/24
    gateway 10.10.84.1
    bridge-ports eno1
    bridge-stp off
    bridge-fd 0
    
iface enp1s0f0 inet manual

iface enp1c0f1 inet manual

/etc/hosts

127.0.0.1 localhost.localdomain localhost
10.10.84.11 atlas.netdream.local atlas

::1 ip9-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

"ip addr" reports eno1 and vmbr0 being UP
but "ping 10.10.84.1" reports unreachable

Speaking hardware, eno1 is the network port of a "Gigabyte B360M D3P" motherboard while both enp1s0f* come from a "Broadcom BCM5709CC0KPBG" i'd like to passthrough to a VM later on.

Does anyone have any idea what could be wrong ?

Network config looks good to me, assuming that the addresses/subnet mask are correct. Any suspicious messages in dmesg/journalctl? Have you verified that the switch you are connected to works as expected? Maybe some faulty cable?

I reached out to my network team and ... THEY screwed up
They tagged the network port on the wrong VLAN so proxmox couldn't reach this gateway.

Sorry for the useless post

Stuff like this just happens sometimes

I'm glad everything is working now. Thanks for marking the thread as 'resolved', by the way!
