unable to bind LXC in multiples vlan interfaces

[emanuelx]

Hi,

I have configured on my unifi device 3 vlans.

• 192.168.0.1/24 vlan1
• 192.168.10.1/24 vlan10
• 192.168.100.1/24 vlan100

proxmox is On vlan 3

and this is my network configuration

auto lo
iface lo inet loopback

iface enp35s0 inet manual
#NET1

iface enp36s0 inet manual
#NET2

iface enx8a85176696bf inet manual
#BCM

iface enxee5383e5e69d inet manual

iface enx7263353e94e6 inet manual

auto vmbr0
iface vmbr0 inet static
        bridge-ports enp35s0
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094
#10, 100

auto vmbr1
iface vmbr1 inet static
        address 192.168.100.240/24
        bridge-ports enp36s0
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094

auto vmbr0.100
iface vmbr0.100 inet static
        address 192.168.100.50/24
        gateway 192.168.100.1
        mtu 1280

auto vmbr0.10
iface vmbr0.10 inet static
        address 192.168.10.2/24

My proxmox Web GUI is living on 192.168.100.50

In pihole and wordpress( with Apache) I have configured two interfaces

Pihole and wordpress have the same configuration but the IP off course is different.




I checked the services is not biding to a specific IP, so the configuration on services are OK.

After I start up the containers, I'm able to ping all ips from my pc inside vlan 10.

The pihole case is, sometimes works other times doesn't work.

On WordPress side, only binds the port into first interface.

I don't know what is wrong with my configuration.

Some updates:

LXC container with 3 interfaces - working Fine

• 192.168.100.211
• 192.168.100.212
• 192.168.100.213

LXC container with 4 interfaces - vlan 100 is working fine

• 192.168.100.211
• 192.168.100.212
• 192.168.100.213
• 192.168.60.211 -> not working

LXC container with 5 interfaces - after add vlan 10, the other ips stopped from working

• 192.168.100.211
• 192.168.100.212
• 192.168.100.213
• 192.168.60.211
• 192.168.10.211 -> only works this interface

For some reason I notice this only happens on old lxc contaners, new containers debian/ubuntu as the expected behaviour.
