GRE Tunnel for DDos protection

[stanbrug]

Hello. I am new to Proxmox and I hope you guys can help me with setting up an GRE tunnel.

I have a working GRE tunnel from a OVH VPS to a Hetzner dedicated server running Proxmox. The GRE tunnel is for using the DDoS protection of OVH.

So this is my situation, I have a interface on my proxmox server, gre1, where the ports i need on the vm are routed to from OVH with iptables. And i want to use this interface as my network card in a proxmox VM. How can i do that?

Hello,

This isn't a proxmox need xD

Create a vmbr w
Containing all vm wanted behind.
Use iptables for forwarding your traffic into your tunnel
