Hetzner Network problem

[DamienH]

Hello every one
I try to find my answers in the froum but it seems that i miss somthing in my configuration .
Hetzner provide two type of ip address
1- Single ip address with mac-address
2- Subnet IP address
I want to use both of them in my network configuration .
I face problem with single ip address .
I configure my host just like other clients here in this froum but it didnt work for me .
Here is my network configuration :

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback


auto enp9s0
iface enp9s0 inet static
        address 248.251.179.120/27
        gateway 248.251.179.97
        up route add -net 248.251.179.96 netmask 255.255.255.224 gw 248.251.179.97 dev enp9s0
# route 248.251.179.96/27 via 248.251.179.97

auto vmbr0
iface vmbr0 inet static
        address 248.251.179.120/32
        bridge-ports none
        bridge-stp off
        bridge-fd 0
        post-up echo 1 > /proc/sys/net/ipv4/ip_forward
        up ip route add 248.251.179.122/32 dev vmbr0
        up ip route add 248.251.179.124/32 dev vmbr0

I set the mac address for the network of the server but it get no network .
Can you please help me solve the problem ?

This should be for the PVE host, right?

Does the subnet work on a Linux or LXC? - is yes, this should work on the Windows VM as well (maybe you have to set the IP manually in the Window's VM)

I find the problem and fix it
I install this Proxmox server with hetzner image installer and it configure the enp9s0 to static
I change it to manual and everything is fixed !
So i have go to the next level
I configure my subnet on vmbr1 and my single ips on vmbr0
My subnet is routed to one of my single ip address and i install mikrotik to have better management .
I want my subnet and my single ips reachable from one bridge .
I search the froum and i find someone suggest to use veth option .
auto veth_vmbr1 iface veth_vmbr1 inet manual link-type veth veth-peer-name veth_vmbr2 auto veth_vmbr2 iface veth_vmbr2 inet manual link-type veth veth-peer-name veth_vmbr1 auto vmbr1 iface vmbr1 inet manual bridge_ports veth_vmbr1 auto vmbr2 iface vmbr2 inet manual bridge_ports veth_vmbr2
I configure the network look like that but i cannot choose veth_vmbr0 OR veth_vmbr1 on my vms .
Also i check the netowrk there is nothing changed when i use vmbr0 i cannot assign subnet ip address Or when i use vmbr1 i cannot use single ip address there .
Can you please help me fix this ?
