We have a LoadBalancer and want to use it with multiple OVH VPS as a proxy.
I intend to secure the VPS with the firewall provided by OVH which allows to block connections before the routing and thus before they touch the VPS.
I was wondering if in order for the loadbalancer to access the machine and transfer the requests, all the IP ranges of Cloudflare must be accepted by the firewall ?
If this is not the case, does the LoadBalancer Spoof the requests sent with the original IP to the original servers?
Thanks in advance
