This is a nifty little device for under £100 suitable for a home router.

I am using one running OpenBSD 6.8 for my AAISP PPPoE connection (avoiding the supplied VMG1312-B10A which has a number of issues).

Installation

I bought a SanDisk 16GB USB stick as there were reports the supplied USB stick isn't particularly reliable, plus it's nice to keep it separate in case of backup or selling the device in the future.

Download the OpenBSD miniroot68.img file system and dd(1) it, for example on macOS (assuming /dev/disk2):

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:

# Config that is very close to a i3 window manager's keybinding.

set -s escape-time 0
setw -g aggressive-resize on

# First remove *all* keybindings
unbind-key -a

# List keys
bind-key ? list-keys

#!/usr/bin/env python
# vim: set fileencoding=utf-8
#
# USAGE:
# Back up your tmux old config, run the script and redirect stdout to your conf
# file. Example:
#
#   $ cp  ~/.tmux.conf  ~/.tmux.conf.orig
#   $ python ./tmux-migrate-options.py  ~/.tmux.conf.orig  >  ~/.tmux.conf
