Configuring IPv6 block from Online.net On Proxmox Host and Guests

Following the documentation on online.net would get IPv6 to work only in a simple system installation but won't get IPv6 to work with virtualization environment (Exp. Proxmox) as It's missing some IPv6 forwards and proxies on sysctl.conf.

On Proxmox Host (Or Debian if single Debian Installation)

Enable IPv6 on the System:

• Change Module Options to Enable IPv6:

I ran into the battle of running all of my VMs and the host node under a single public IP address. Luckily, the host is just pure Debian, and ships with iptables.

What needs to be done is essentially to run all the VMs on a private internal network. Outbound internet access is done via NAT. Inbound access is via port forwarding.

Network configuration

Here’s how it’s done:

Create a virtual interface that serves as the gateway for your VMs:

#!/bin/bash

# source: https://gist.github.com/francoisromain/58cabf43c2977e48ef0804848dee46c3
# and another script to delete the directories created by this script
# project-delete.sh: https://gist.github.com/francoisromain/e28069c18ebe8f3244f8e4bf2af6b2cb

# Call this file with `bash ./project-create.sh project-name`
# - project-name is mandatory

# This will creates 4 directories and a git `post-receive` hook.

get_latest_release() {
  curl --silent "https://api.github.com/repos/$1/releases/latest" | # Get latest release from GitHub api
    grep '"tag_name":' |                                            # Get tag line
    sed -E 's/.*"([^"]+)".*/\1/'                                    # Pluck JSON value
