Hi there
got new Hardware and setting up proxmox new.

my old config look like this:


Code:
auto lo
iface lo inet loopback


iface enp0s31f6 inet manual

iface enp4s0 inet manual

iface enp4s0.20 inet manual

auto enp0s31f6
iface enp0s31f6 inet static
    address 10.0.0.10/24
    gateway 10.0.0.254
    bridge-ports enp0s31f6.5
    bridge-stp off
    bridge-fd 0


auto vmbr20
iface vmbr20 inet manual
    bridge-ports enp4s0.20
    bridge-stp off
    bridge-fd 0


this has worked for years now...

My new config

Code:
auto lo
iface lo inet loopback

iface enp9s0 inet manual

iface enp12s0 inet manual

iface enp13s0 inet manual

iface enp14s0 inet manual

iface enp15s0 inet manual

auto enp12s0.20
iface enp12s0.20 inet manual

auto enp12s0.90
iface enp12s0.90 inet manual

auto enp9s0.5
iface enp9s0.5 inet manual

auto vmbr0
iface vmbr0 inet static
    address 10.0.0.10/24
    gateway 10.0.0.254
    bridge-ports enp9s0.5
    bridge-stp off
    bridge-fd 0

auto vmbr20
iface vmbr20 inet manual
    bridge-ports enp12s0.20
    bridge-stp off
    bridge-fd 0

auto vmbr90
iface vmbr90 inet manual
    bridge-ports enp12s0.90
    bridge-stp off
    bridge-fd 0

i'm not able to ping anything from the vm, also can't ping host -> vm or vm-> host.

did something change with proxmox 7 or do i have something wrong?

VLAN 5 on Networkcard 1 is working good, but the VLAN's on Card 2 are not... the Networkcard is the same, only the names changed with new Hardware

Hi,

you could try to add the auto keyword for each interface. Without this, the interfaces won't come up automatically at boot.
 
hi there

i found out, with my internal NIC it's working. But the second NIC (4 Port Ethernet Card) will not work :( but in the old "Server" they worked...

Internal NIC (working):
Code:
root@proxmox:~# ethtool -i enp9s0
driver: r8169
version: 5.11.22-1-pve
firmware-version: rtl8168h-2_0.0.2 02/26/15
expansion-rom-version:
bus-info: 0000:09:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: no

external 4 Port NIC (not working)
Code:
root@proxmox:~# ethtool -i enp12s0
driver: r8169
version: 5.11.22-1-pve
firmware-version: rtl8168g-2_0.0.1 02/06/13
expansion-rom-version:
bus-info: 0000:0c:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: no

i also try'd to install Realtek driver from the official Homepage:

Code:
root@proxmox:~# ethtool -i enp12s0
driver: r8168
version: 8.049.02-NAPI
firmware-version:
expansion-rom-version:
bus-info: 0000:0c:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: no
root@proxmox:~#


Code:
root@proxmox:~# dmesg | grep enp12

root@proxmox:~#

it seems the onboard chip is the same as the 4-port nic.

Code:
root@proxmox:~# lspci | grep -i net
