I need help for network configuration in proxmox.
I have a server in hetzner with an additional ip and its respective separate mac. Following the instructions given in this tutorial
https://community.hetzner.com/tutorials/install-and-configure-proxmox_ve?title=Proxmox_VE/en
Network Configuration Host Bridged

IP host proxmox 95.217.xx.xx/26
ip adicuional 95.217.xx.xx/26
Mac separada 00:50:56:00:xx:xx

The configuration of my /etc/network/interfaces file
Network Configuration Host Bridged

Code:
# /etc/network/interfaces
### Hetzner Online GmbH - installimage
# Loopback device:
auto lo
iface lo inet loopback

iface enp1s0 inet manual

auto vmbr0
iface vmbr0 inet static
  address 95.217.198.xx
  hwaddress 00:50:56:00:xx:xx # MAC address of the NIC, required since Proxmox 7.0
  netmask 255.255.255.192
  pointopoint 95.217.xx.xx
  gateway 95.217.xx.xx
  bridge_ports enp1s0
  bridge_stp off
  bridge_fd 1

# for a subnet
auto vmbr1
iface vmbr1 inet static
  address 95.217.198.xx # additional ip
  netmask 255.255.255.192
  bridge_ports none
  bridge_stp off
  bridge_fd 0

I can't get the machines hosted in proxmox to have internet and to be accessible from the outside.

Any idea what is happening

Host Bridged configuration of this tutorial makes no sense to me.

It should be something similar to:
Host
Code:
# /etc/network/interfaces
# Loopback device:
auto lo
iface lo inet loopback

iface enp1s0 inet manual

auto vmbr0
iface vmbr0 inet static
  address 95.217.198.xx
  netmask 255.255.255.192
  pointopoint 95.217.xx.xx
  gateway 95.217.xx.xx
  bridge_ports enp1s0
  bridge_stp off
  bridge_fd 1

Client
Code:
# /etc/network/interfaces
# Loopback device:
auto lo
iface lo inet loopback

# device: ens18
auto ens18
iface ens18 inet static
  address <additional IP>
  netmask 255.255.255.255
  pointopoint <gateway of the additional IP>
  gateway <gateway of the additional IP>

In VM config use vmbr0 as bridge and assigned virtual MAC as MAC address.

This is exactly how I do it, but it doesn't work, the vm's take the ip but they don't have internet connection nor are they accessible from outside.
I opened a ticket with hetzner to have, which is what they tell me because apparently there is some kind of problem with the additional IP given. :mad::mad::mad::mad:
