VM is not getting internet.

[parvezbd]

Hi Dear,

I am new at proxmox. for learning purpose, I have installed proxmox in Oracle Virtual Box on an windows 11 machine(host). Host machine(windows) IP is 192.168.0.194/24 (Auto DHCP connected with a home router). The ProxMox is in Oracle Virtual Box and connected as bridge network (Proxmox ip 192.168.0.150/24).

I have installed a linuxOS in proxmox with auto DHCP and got the ip 192.168.0.177 automatically using default vmbr0 Linux bridge (connected with enp0s3, the only adapter). From Proxmox shell, I can ping 8.8.8.8 (google) and 192.168.0.177 (VM). In this point, from the VM, I can ping 192.168.150 (Proxmox OS), but I can't ping 192.168.0.194 (host machine) or 8.8.8.8.

Can anyone guide me to resolve this Networking problem?
[apologize for my poor English]

Sincerely
Parvez

hi !
Check -> in your VM:
- /etc/network/interfaces
- /etc/resolv.conf

hi !
Check -> in your VM:
- /etc/network/interfaces
- /etc/resolv.conf

- /etc/network/interfaces
auto lo
iface lo inet loopback

iface enp0s3 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.0.150/24
gateway 192.168.0.1
bridge-ports enp0s3
bridge-stp off
bridge-fd 0

auto vmbr1
iface vmbr1 inet manual
bridge-ports none
bridge-stp off
bridge-fd 0

auto vmbr2
iface vmbr2 inet manual
bridge-ports none
bridge-stp off
bridge-fd 0

cat /etc/resolv.conf
search Dlink
nameserver 192.168.0.1

What to do now?

My guess would be that you need to add 1.1.1.1 or 8.8.8.8 as additional DNS server. so it would add the following:
nameserver 8.8.8.8
nameserver 1.1.1.1
before
nameserver 192.168.0.1

that is how I have mine configured

this isn't the VM config file ?
- /etc/network/interfaces

auto lo
iface lo inet loopback

iface enp0s3 inet manual

auto vmbr0
iface vmbr0 inet static
       address 192.168.0.150/24
       gateway 192.168.0.1
       bridge-ports enp0s3
       bridge-stp off
       bridge-fd 0

auto vmbr1
iface vmbr1 inet manual
       bridge-ports none
       bridge-stp off
       bridge-fd 0

auto vmbr2
iface vmbr2 inet manual
       bridge-ports none
       bridge-stp off
       bridge-fd 0

if yes it's wrong, it should look like this

auto ens18
iface ens18 inet static
    address 192.168.22.2/24
    gateway: 192.168.22.254
    dns-nameserver 8.8.8.8 8.8.4.4
    dns-nameserver 192.168.1.254
