Machine in Proxmox Cannot ping gateway | Proxmox in VM VirtualBox

[goenzz]

I'm sorry to ask this..
I have tried to find a solution from the forum and proxmox wiki, but to no avail..

[Problem]
on the proxmox installed in the oracle vm virtualbox I provide a host-only network configuration for the private lab.
on the proxmox I installed an ubuntu-server.22.04 vm, the vm gets an ip, but cannot ping to the gateway or cannot be accessed by my windows host.
can only ping to proxmox only, what solution can I get?

[Network Configuration in Proxmox]
auto lo
iface lo inet loopback

iface enp0s3 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.2.3/24
gateway 192.168.2.1
bridge-ports enp0s3
bridge-stp off
bridge-fd 0

source /etc/network/interfaces.d/*

what should i do?
thank you..

Hi,

The question in the first place, may I ask you why you install Proxmox VE inside the VirtualBox? Did you follow our wiki [0] below link?
