can not ping proxmox server

[taich]

I have a proxmox server with 1 NIC.

This is my network configuration:

auto lo
iface lo inet loopback
iface lo inet6 loopback

iface eth0 inet manual

auto vmbr0
iface vmbr0 inet static
    address 10.10.0.34/24
    gateway 10.10.0.1
    bridge-ports eth0
    bridge-stp off
    bridge-fd 0
    bridge-vlan-aware yes
    bridge-vids 2-4094
#LAN

iface vmbr0 inet6 static
    address 2001:xxxx:xxxx::34/64
    gateway 2001:xxxx:xxxx::1


auto vmbr0.227
iface vmbr0.227 inet static
    address xx.xx.xx.82/24
    bridge-ports eth0
    bridge-stp off
    bridge-fd 0
    bridge-vlan-aware yes
    bridge-vids 2-4094
#WAN

iface vmbr0.227 inet6 static
    address 2001:xxxx:xxxx::82/64

I can ping the local IP but I can't ping the WAN IP.
Neither from inside nor from outside.

I have some virtual machines with WAN access. These VM's can be reached from outside.

I have no explanation for that.
Any help would be greatly appreciated.

Just found the reason. Wrong Gatway.
