Hetzner second IP address

[haroldas194]

A bit info about setup:
I ordered second IP for my server and I would like to use it to provider internet connectivity to my VMs in NAT

Config:

auto lo
iface lo inet loopback

iface lo inet6 loopback

auto enp3s0
iface enp3s0 inet static
    address MAIN IP/32
    gateway MAIN IP GW
    pointopoint MAIN IP GW

auto enp3s0:1
iface enp3s0:1 inet static
    address SECOND IP/32
    gateway SECOND IP GW
    pointopoint SECOND IP GW

auto vmbr0
iface vmbr0 inet static
    address 10.10.10.1/24
    bridge-ports none
    bridge-stp off
    bridge-fd 0
#VM internal range

        post-up   echo 1 > /proc/sys/net/ipv4/ip_forward
        post-up   iptables -t nat -A POSTROUTING -s '10.10.10.0/24' -o enp3s0:1 -j MASQUERADE
        post-down iptables -t nat -D POSTROUTING -s '10.10.10.0/24' -o enp3s0:1 -j MASQUERADE

:1 interface seems to be inactive in Proxmox panel but works ( I can access Proxmox with it)

It's the notation for a second IP not exactly a separate interface.

But what's your question?
