[hokaloh]

Hi Everyone, hope everyone can solve my problem, dont what the problem .

Im add bridge vmbr0 using cli at the file "/etc/network/interfaces.new" like this -->

auto lo iface lo inet loopback iface ens4 inet manual auto vmbr0 iface vmbr0 inet static address 192.168.0.3 netmask 255.255.255.0 gateway 192.168.0.1 bridge_ports ens4 bridge_stp off bridge_fd 0

After that, it display on the gui interfaces network vmbr0 . on proxmox same it change interface.

Hey,

the interface config looks fine, do you have a DHCP server running on 192.168.0.0/24? If not you have to configure a static IP in your VM. If you do have a DHCP server, could you post the output of [sudo] dhclient.

Can you ping your gateway(192.168.0.1) from the VM? Could you post the output of ip a and ip r.

But you can ping 192.168.0.1 from PVE? Did you change anything in the firewall?

Same cannot ping too 192.168.0.1 from PVE


this my network interfaces PVE, what sould i do ?

I assume 192.168.0.1 is your router. Can you check if the router is actually on the same network? Maybe ping PVE from your router, depending on whether that is possible with the device you have.

You have to set up NAT as described in 3.3.6 [1].
