[SOLVED] Proxmox guest VM IP setup

[izghitu]

Hi,

I have a Proxmox server running on Debian 10. It is new and I am trying to properly setup the networking for the gues VMs. I need to be able to set each guest VM with its own external IP.

On proxmox Host I have this:

cat /etc/network/interfaces
...
auto enp65s0f0
iface enp65s0f0 inet static
        address 192.80.131.4/24
        gateway 192.80.131.1
        dns-nameservers 8.8.8.8 1.1.1.1

auto vmbr0
iface vmbr0 inet static
        address 192.80.131.5
        netmask 255.255.255.0
        bridge-ports none
        bridge-stp off
        bridge-fd 0
        up ip route add 192.80.131.6 dev vmbr0
        post-up iptables -t nat -A POSTROUTING -s 192.80.131.0/24 -o vmbr0 -j MASQUERADE
        post-up iptables -t nat -A POSTROUTING -s 192.80.131.0/24 ! -d 192.80.131.0/24 -o enp65s0f0 -j MASQUERADE

On guest VM:

cat /etc/netplan/50-cloud-init.yaml
network:
    ethernets:
        ens18:
            addresses:
            - 192.80.131.6/24
            gateway4: 192.80.131.5
            nameservers:
                addresses:
                - 8.8.8.8
    version: 2

And I have ipv4 forwarding enabled.

I do get the internet connection on the guest VM but when I check the external IP using "curl ipecho.net" I get the IP of proxmox host.

What I need is for each guest VM to have its own external IP that I setup. I own the whole 192.80.131.0/24 CIDR and I need to run as many VMs as I want that will have its own external IP.

Is there any guide that shows how I need to setup the networking, routing and firewall rules in order to achieve this?

Please help
Thanks in advance.
