Set up network for vm on Hetzner robot

[stefano_gr1992]

Good morning,

I have searched far and wide on the internet, even tried hetzner's own guide, I cannot configure my vm's network on proxmox.

I have installed on windows server 2019 on the virtual machine, but I need to make it comiunicate with the outside making it reachable via rdp.

I am at my wits end any help would be appreciated.

Thanks

Hi,

Please Post the network configuration from your Proxmox VE and the Windows server 19 VM.

Do a network Konfiguration like this

cat /etc/network/interfaces
auto lo
iface lo inet loopback

# extern
auto eno1
iface eno1 inet dhcp
    
    
# intern
auto vmbr0
iface vmbr0 inet static
    address 10.0.0.1/24
    bridge-ports none
    bridge-stp off
    bridge-fd 0

then you need to enable ip forwarding

cat /etc/sysctl.d/lihas.conf
net.ipv4.forward = 1

and set firewall rules to masquerade you internal IPs and to dnat your external ip to your server

You cannot just bridge your vm to your network card, the additional mac will be detected and your network blocked.

Do a network Konfiguration like this

cat /etc/network/interfaces
auto lo
iface lo inet loopback

# extern
auto eno1
iface eno1 inet dhcp
   
   
# intern
auto vmbr0
iface vmbr0 inet static
    address 10.0.0.1/24
    bridge-ports none
    bridge-stp off
    bridge-fd 0
