Can't access internet from VM

[RTV4]

Hello,
I have multiple public IPv4 addresses, and I would like to give each VM its own dedicated IP address.

After installing the VM, I found that I can only ping the IP address of the host server, but I cannot ping the gateway or 1.1.1.1 from the VM.

I can ping everything from the host server, including the IP address of the VM.


I've tried searching the forum and google, but unfortunately I only find threads that address one public IPv4 for all VMs and proxmox.

Anyone know how to make VMs accessible from the internet please?

I have /etc/network/interfaces set up like this:
on host server:

auto lo
iface lo inet loopback

iface enp34s0 inet manual

iface enp41s0 inet manual

iface enx1a3de1cdf94d inet manual

auto vmbr0
iface vmbr0 inet static
        address 188.130.232.200/24
        gateway 188.130.232.1
        bridge-ports enp34s0
        bridge-stp off
        bridge-fd 0

on VM:

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

allow-hotplug ens18
iface ens18 inet static
        address 188.130.232.201/24
        gateway 188.130.232.1
        dns-nameservers 1.1.1.1
        dns-search testserver

Thank you very much in advance!

some providers need register VM MAC to public ip used.

I contacted my provider, and they said any MAC address should work, even without registration.

I'm not sure but /24 ip block is suspicious.

I have 1U server at a friend's rack who has purchased a /24 subnet, so that should be ok.
