Bare metal servers offered at Scaleway are at reasonable prices, which can be compared to those on Hetzner. You even get Proxmox installation by default contrary to Hetzner were you need to install Debian first. To setup Proxmox with one public IP anf pfSense with another one you need to order Flexible IP and request for virtual MAC address. Remember that on Scaleway’s flexible IPs gateway is fixed and it is 62.210.0.1. Then for the network configuration: x.x.x.x is primary Proxmox public IP. y.y.y.y is its gateway (with a.a.a.a network with b.b.b.b netmask). z.z.z.z is then your secondary public IP
