Hello, I currently have a small-ish operation on OVH, I am looking to move to Hetzner however need to keep my IPs from my OVH setup plus OVH's superior DDoS protection helps.

My main goal in moving to Hetzner is to save money, so naturally, I don't want to have to also buy an equal number of IPs on Hetzner's more expensive system as that defeats the point.

I'm wondering if there's an easy way to have all my IPs from a cheap OVH VPS pointing maybe to my main server IP via something like GRE routing and then on the Proxmox side route these IPs to one per VM so that I don't have to assign them their own unique IPs on Hetzner's side then route directly to that.

My bad if I described this like an idiot, I'm a bit of a networking noob.

Yes, but in a way where the only internet-accessible IPs on the VMs are being provided by the tunnel, so that I don't need 1x Hetzner IP per VM in addition to the 1x Tunnel IP per VM
