Ubiquiti Edgerouter firewall rules for IOT networks

Just going to present several variations on a theme here, tested with a Ubiquiti EdgeRouter 4 in my home lab.

Several resources were consulted in the process of creating these firewall rules, cited below under "Resources".

In these examples, the "default" or "management" VLAN1 is VLAN1, on 192.168.1.0/24. A separate VLAN8 was created for IOT devices on 192.168.8.0/24, along with its own DHCP service on the router.

The minimum requirements here are to have the IOT devices on VLAN8 network get an address from the VLAN8 DHCP server and access the Internet through the VLAN's gateway (192.168.8.1), allow managment network access to the

How to mount a VirtualBox shared folder when the Guest OS boots

Problem

While using VirtualBox's Guest Additions to mount shared folders provides a seamless way to mount shared folders, there are also disadvantages.

• Shared folders will always mount in /media/sf_(share name) unless specified using through vbox drivers in the guest OS
• Mounting does not happen at boot-time. Applications that require paths at boot will not be able to access the shared folder even after it is mounted - such as Docker.

Solution

Instead of relying on Guest Additions, if you have sudo permissions, shared folders can be mounted at boot-time using fstab. Using this approach allows

Deploying Sculpin Sites to GitHub Pages

I wanted to be able to use Sculpin to generate GitHub pages. Here's what I did...

1. Created a super awesome Sculpin site from the Sculpin Blog Skeleton

2. Make sure everything is under version control in my master branch (except things that shouldn't be. see the .gitignore)

3. Updated publish.sh:

#!/bin/bash

lemiorhan

#!/bin/bash

target_branch="production"
working_tree="PATH_TO_DEPLOY"

while read oldrev newrev refname
do
    branch=$(git rev-parse --symbolic --abbrev-ref $refname)
    if [ -n "$branch" ] && [ "$target_branch" == "$branch" ]; then
