Hi,
Before I dive into my question, I want to mention that I've thoroughly explored the entire forum and Hetzner documentation, including relevant topics related to my issue. Despite my efforts, I couldn't find a solution, so I'm opening a new topic. There might be similar threads in the forum, but unfortunately, I couldn't find a resolution.
I have a dedicated server with Hetzner, which provides me with a primary IPv4 and IPv6 /64 address. I've installed Proxmox VE 8.1 on the server, and I can access it using the IPv4 address.
Subsequently, I ordered an IPv4 subnet /28. According to the documentation, this subnet is routed to the main or primary IP. Now, I want to use these subnet IPs and IPv6 addresses in my VMs, employing Routed Configuration. However, I'm unable to reach the internet from my VMs.
Primary IPv4 : 49.23.64.218 - Gateway : 49.23.64.193 - Mask : 255.255.255.192
IPv6 : 2a01:4f8:2200:472d::/64
Additional Subnet IP 183.47.183.64 - Mask : 255.255.255.240 - Broadcast : 183.47.183.79 - (Static routed on 49.23.64.218 by Hetzner)
Here's my network configuration on the host system, similar to the following (IPs are similar but altered):
# Loopback device:
auto lo
iface lo inet loopback
# device: eno1
auto eno1
iface eno1 inet static
address 49.23.64.218
netmask 255.255.255.255
pointopoint 49.23.64.193

I've activated in sysctl.conf the following lines
sysctl -w net.ipv4.ip_forward=1
sysctl -w net.ipv6.conf.all.forwarding=1
