Test doing :
Proxmox --> Local machine : Ping 10.244.4.47 --> Ok
Proxmox --> Gateway : Ping 10.244.4.1 --> Ok
Proxmox --> KVM : Ping 10.244.4.106 --> OK
KVM --> Proxmox : Ping 10.244.4.107 --> OK
KVM --> Local machine : Ping 10.244.4.47 --> FAIL (WHY ?)
KVM --> Gateway : Ping 10.244.4.1 --> FAIL (WHY ?)

How can we resolve this problem ?

Regards

The problem is resolved

The problem was coming of the configuration from the switch. The port was configured to only one connection mac adress.

So KVM could'nt reach the gateway or local network.

Sorry, for my basic english
