No connection on VMclients + need to add multiple IP address on same interface

[anaskhallouqi]

Hello guys,

I would need help configuring my Proxmox server.

I currently have the system installed on a dedicated server with public ip address on port vmbr0. The network interface where there is internet connection is eno1.

I installed Windows Server where I have no internet access despite having configured the vmbr0 card. This is the first problem.

The second problem is that I have several public IPs that I want to associate to each vm.. I tried several configurations, also editing the file /etc/network/interfaces without success.

auto lo
iface lo inet loopback

auto eno1
iface eno1 inet manual

iface eno2 inet manual

auto vmbr0
iface vmbr0 inet static
        address 95.xxx.xxx.xxx/24
        gateway 95.xxx.xxx.xxx
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094

Do you have any news or info about how to solve problems?

Thank you!

Update:

I try this configuration:

/etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eno1
iface eno1 inet dhcp

/etc/network/interfaces.d/*

auto lo
iface lo inet loopback

auto eno1
iface eno1 inet static
        address  95.xxx.xxx.xxx/24
        gateway  95.xxx.xxx.1
        post-up echo 1 > /proc/sys/net/ipv4/ip_forward
        post-up echo 1 > /proc/sys/net/ipv4/conf/eno1/proxy_arp


auto vmbr0
iface vmbr0:0 inet static
        address  45.xxx.xxx.xxx/24
        bridge-ports none
        bridge-stp off
        bridge-fd 0

auto vmbr0
iface vmbr0:1 inet static
        address  92.xxx.xxx.xxx/24
        bridge-ports none
        bridge-stp off
        bridge-fd 0

auto vmbr0
iface vmbr0:2 inet static
        address  92.xxx.xxx.xxx/24
        bridge-ports none
        bridge-stp off
        bridge-fd 0

I also try to put different name on iface vmbr[i]

...

auto vmbr0
iface vmbr0 inet static
...

auto vmbr1
iface vmbr1 inet static
...

auto vmbr2
iface vmbr2 inet static
...

And in the end when i lunch the command ifreload -a it popup me this message:

warning: duplicate interface lo found
error: main exception: [Errno 2] No such file or directory: '/sys/class/net/vmbr1/brif/'

I hope with that additional info can someone understand me and help to solve that issues.

PS: no vm connected to the internet right now.
