what to do if my proxmox provider does not support the Default Bridge Configuration

i have a proxmox server with a single ip addres and that's my correct network configuration :

# network interface settings; autogenerated

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

iface eth1 inet manual

auto vmbr0
iface vmbr0 inet static
        address 1**.2**.2*.**/24
        gateway 1**.2**.2*.1
        bridge-ports eth0
        bridge-stp off
        bridge-fd 0

        up ip route replace via 1**.2**.2*.1 dev vmbr0

but my provider did not give me an ip range to use with the vms,
i have take a look for the Routed Configuration, but i think i need both ip a public IP address and an additional IP block for the VMs,
so how can i get them? isn't my proxmox server's ip is the public ip? then from where can i get the additional ip block?
to be honest i'm not that good at the networking and i need to configure my network to give internet access to the vms and cts.

if you have only 1 public ip address for your server, and 0 additionial public ip for your vms,

the only way, is to use private ips inside yours vms, and do port redirection with iptables rules, but it's pretty limited (port 80 -> vm1, port 22 -> vm2,....)

(tldr: you should by extra ips to your provider)
