Hi,

We have a cluster with two servers @ hetzner. Each one with it's uplink for WAN, let's say eno3 on each one.
We also have another two interfaces connected to a switch, so each server will communicate to each other over the LAN.

eno3 --- bridge --> vmbr0 (WAN Internet access)
eno 1 & eno2 -- connected to switch ---> bond0 on proxmox server (active-backup)
vmbr1 --> bridge for bond0 -- access to LAN

We also have a vSwitch from Hetzner with a /29 subnet IPs associated over a VLAN (first ip from /29 is the gateway from Hetzner -- different from the main IP which is on eno3 interface).

We configured eno3.VLANID interface with no IP address on it and then created vmbr2 (no ip address assigned) bridge for eno3.VLAN

On one of our VM created on the Host, we added an interface eno1 -- from vmbr2 and assigned a public IP address from that /29 subnet.
Everything is working well, we are able to access the internet from the VM with that IP, and we can be reached from the internet using that IP.

The problem is when we try to enable the Firewall from Proxmox interface, we can be accesed from outside, but we're not able to access anything outside from that VM.

We tried the following:
1.1. Enable Firewall on Data center:
Input Policy: DROP
Output Policy: ACCEPT
1.2. Enable Firewall on host level:
1.3. Enable Firewall on VM interface:
Input Policy: DROP
Output Policy: ACCEPT
Using this config we're unable to access the VM from outside (which should be ok), but we are also not able to access the internet from the VM.


The second test we made was:
Input Policy: ACCEPT on all levels (datacenter, VM)
Output Policy: ACCEPT on all levels.

We can be accessed from the internet, but we are still unable to access the internet from VM.

After reading some other posts on this forum, I tried to disable ebtables and reboot the host..but the results are still the same.

We installed proxmox using the Proxmox VE 6.0 ISO Installer.

/etc/network/interfaces
Code:
auto lo
iface lo inet loopback

auto eno3
iface eno3 inet manual

iface eno4 inet manual

iface eno1 inet manual

iface eno2 inet manual

auto eno3.4010

    gateway  XX.XX.XX.129
    bridge-ports eno3
    bridge-stp off
    bridge-fd 0
    bridge-vlan-aware yes
    bridge-vids 2-4094
#WAN Interface

auto vmbr1
iface vmbr1 inet static
    address  YY.YY.YY.10
    netmask  24
    bridge-ports bond0
    bridge-stp off
    bridge-fd 0
#LAN Interface

auto vmbr2
iface vmbr2 inet manual
    bridge-ports eno3.4010
    bridge-stp off
    bridge-fd 0
    bridge-vlan-aware yes
    bridge-vids 2-4094
#VLAN Interface for vSwitch


Anyone any ideea ?
Thanks in advance!
