I have a very simple networking setup, as below:
This setup works to allow me to access the host from my laptop on VLAN 10, on any of the 4 IP addresses (.206 to .209) when I have the ports in UNTAGGED mode on my switch, but I can not access the host after switching the ports to TAGGED for VLAN 10.
I suspected this may be due to vmbr1 not being VLAN aware, so I attempted to enable that (identical to the vlan aware flag on vmbr0); unfortunately this made the host inaccessible whether the ports were tagged or untagged, and I had to remove the VLAN aware flag in order to access the host again. This is very unexpected behaviour.
I have tried a full reinstall of Proxmox, but to no avail. I have a separate physical server with both its interfaces VLAN aware and operating in TAGGED mode, which works as expected so I am confident this is not a switch config issue but something I'm missing in my Proxmox configuration.
Can anyone shed any light on why making the bridge VLAN aware renders the entire host inaccessible on any address?
Code:
auto lo
iface lo inet loopback
iface eno1 inet manual
#port 28
auto eno2
iface eno2 inet manual
#port 27
auto vmbr0
iface vmbr0 inet static
address 192.168.5.206/24
gateway 192.168.5.1
bridge-ports eno1
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 2-4094
auto vmbr0.10
iface vmbr0.10 inet static
address 192.168.5.208/24
auto vmbr1
iface vmbr1 inet static
address 192.168.5.207/24
bridge-ports eno2
bridge-stp off
bridge-fd 0
auto vmbr1.10
iface vmbr1.10 inet static
address 192.168.5.209/24
