Create DNS-over-TLS bridge with Pi-hole, unbound and stubby on Ubuntu Server

Few months ago, I've made a similar work but I wanted something a little more easier to manage. Please have a look at here for my previous work.

This time, I'm gonna do pretty much the same thing but using Pi-hole as base then modify it to include unbound and stubby.

This way, I can use the power of Pi-hole with some additional security layers:

• Recursive DNS check (unbound)
• DNS-over-TLS (stubby)

Routing between two UniFi USG based LANs with ZeroTier

Intro

This is a quick explanation of how to configure both ZeroTier and two Ubiquiti UniFi USGs to allow routing between two IPv4 networks. Both networks are in private (RFC1918) address space and each one has its own DHCP service. There is no need for NAT between them, only IP routing.

The two networks are 192.168.1.0/24 (call this the "left" network) and 192.168.10.0/24 (the "right" network) but they can be anything. Also, you can have multiple CIDR blocks on one side or the other of the ZeroTier route; if you do, you just have to create more routing table entries.

How to install Homebrew package manager on Steam Deck

You can install Homebrew (a package manager for macOS and Linux) without disabling the read-only partition with sudo steamos-readonly disable.

Add the following chunk to your existing ISC dhcpd.conf file.

if exists user-class and ( option user-class = "iPXE" ) {
    filename "http://boot.smidsrod.lan/boot.ipxe";
}
else {
    filename "undionly.kpxe";
}
