Hetzner Setup

[etron770]

related to a first question at the debian forum, i would like to know wether this howto is correct for Proxmox
https://wiki.hetzner.de/index.php/Proxmox_VE#Netzwerkkonfiguration_Hostsystem_Routed

The question is, why is the last IP of the subnet not working. I checked the MAC and the Ip more than twice

Since I don't know your provider's rules in detail I cannot guarantee that the following is applicable. However, it's very probable and assuming you've configured the proper MAC addresses you've got configure as described in section
"Netzwerkkonfiguration Bridged".
