Hi,

i've a machine with proxmox v1.9 and i'm trying to build e guest debian 6 install with networking.

I downloaded the template e created the VM.

My trouble start with networking. I can't find a way to see the guest debian on the internet.

Can someone help me to understand venet usage ?

Thanks in advance


Addition info:
I have two public ip addresses assigned by my ISP. These addresses are in different subnets and my provider send all traffic relevant for those IPs to the eth0 on the host Proxmox. If i try to ping these addresses i can see the traffic on the ethernet interface eth0 on proxmox host (with tcpdump).

Public ip address of proxmox: 111.111.111.111/24
Default gateway for proxmox: 111.111.111.254

Ip address for guest: 222.222.222.222/32

This if the config of interfaces on host:
Code:
