[SOLVED] No internet access for VMs

[sylvain65]

Hello community!

I have a big problem on my virtual machines. They don't access to internet. This is a server in our company, not in an external datacenter.
In attachment the configuration of the linux bridge vmbr0 and the network card of the vm windows.
The firewall is disabled for the vm. The ISP address is 192.168.1.254.
vmbr0 address is 192.168.1.12
The virtual machines can ping vmbr0 and machines on the same network but can't acces to internet or ISP router.
So I don't understand. Does anyone have an idea ?
Thank you

hi,

can you ping 192.168.1.254 from inside the VM?

 

[sylvain65]

Hello, no i can't. Destination host unreachable

 

[oguz]

can you try setting 192.168.1.12 as gateway in your VM?

I just tested and no changes. My vmbr0 can ping my ISP router (i specify)

And also if it can help, my proxmox can't ping vms

the first screenshot is the network configuration from your PVE host? or is it a VM?

can you post the output of:

cat /etc/hosts
cat /etc/network/interfaces

do you have firewall enabled?

Hello
it was a problem on an intermediate switch. Before the ISP router. I had to completely reset it there didn't seem to be any blocking by mac address or anything else.
Thank you
