Network Subnet Config Hetzner

[Delein]

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.

Try it using proxy arp, see example https://pve.proxmox.com/wiki/Network_Configuration#_routed_configuration
See also some basic information https://en.wikipedia.org/wiki/Proxy_ARP

I have adden tow rows of code to the eno1 and thats it.


post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up echo 1 > /proc/sys/net/ipv4/conf/eno1/proxy_arp
