Network Subnet Config Hetzner


New Member

Hello Guys,

i am too stupid to configure my Hetzner Proxmox Server. I spend 2 Weeks to configure the Subnet from Hetzner. But it doesn't work.

I have one Nic, One Public IP on eno1 and a Subnet /29 from Hetzner.

The first picture is the network config from the Proxmox Hetzner Server.

The Second picture is the windows Server 2012 VM with the Subnet IP.

I only can ping from outside the Main Subnet IP which is setting up at the Promxo Server interfaces.

The VM has no connection to the internet but i don´t no why.

I hope that anyone can help me.
