I currently own a devoted travel router, and it does a respectable task of linking my gadgets to unknown Wi-Fi networks when I am far from home. I desired something that offered me more control over my network and made accessing my homelab simpler while taking a trip. I currently utilize Tailscale and Headscale throughout a number of gadgets, so explore them on a Raspberry Pi appeared like a natural next action.
What I wound up with was a little networking setup that might do more than share a web connection. By integrating Linux networking tools, Tailscale, and my self-hosted Headscale control server, I might link to my home network, path traffic through a remote connection, and explore various methods to handle my gadgets while away.
My devoted travel router was inadequate
I desired more control over my network
I run a number of services in my homelab, and accessing them from another location is something I routinely require. I might set up Tailscale on specific gadgets, I desired to experiment with a setup that offered me more networking versatility.
A Raspberry Pi was a great prospect due to the fact that it runs a routine Linux distro, supports typical networking energies, and offers me significantly more liberty to set up routing and network services. I can likewise utilize it for other homelab experiments rather of purchasing another devoted networking device.
The concept was to integrate the mobility of a travel router with the versatility of a little Linux device. Tailscale would manage personal connection, Headscale would offer the self-hosted control aircraft, and Linux would look after the networking setup.
Establishing Tailscale and Headscale on my Raspberry Pi
Linking the Pi to my self-hosted tailscale
I began with Raspberry Pi OS and set up the Tailscale customer, it’s rather easy-peasy. I utilize Headscale as well, an open-source, self-hosted execution of the Tailscale control server.
Headscale lets me handle my own coordination server instead of depending upon Tailscale’s hosted control aircraft. I can sign up gadgets, handle my tailnet, and preserve control over the coordination facilities while continuing to utilize the main Tailscale customers.
As soon as I validated the Raspberry Pi with my Headscale server, it appeared together with my other gadgets. I can access it utilizing its Tailscale IP address.
This offered me a practical method to handle the Pi from another location without exposing its SSH service to the general public web. It likewise implied I might incorporate the travel router into the exact same personal network I currently utilize for my homelab.
The next action was setting up the Pi as an exit node. This permits other gadgets linked to my tailnet to path their web traffic through the Raspberry Pi. I allowed IP forwarding and promoted the exit node with:
sudo tailscale up --advertise-exit-node Later, I authorized the exit node through my Headscale setup and made it offered to other gadgets. The precise approval procedure depends upon the Headscale variation and setup. There is another part of the setup worth understanding. Tailscale supports both exit nodes and subnet routers, and they serve various functions.
An exit node paths web traffic through the chosen gadget. A subnet router permits gadgets on your tailnet to gain access to devices on a network behind the Raspberry Pi. If you wish to reach services on a regional network, subnet routing works, and if you wish to path your basic web traffic through a remote connection, you can utilize an exit node.
To turn the Raspberry Pi into a more conventional travel router, I likewise configured its cordless gain access to point, DHCP, NAT, and firewall program guidelines. This lets other gadgets link to the Pi’s regional network without needing every one to have actually Tailscale set up. I have actually released the total setup, setup scripts, and setup directions in my pi-tailscale-travel-router GitHub repositoryso you can utilize it as a beginning point for your own setup.
What can I make with my Raspberry Pi travel router
I would not state that the Raspberry Pi makes my devoted travel router outdated. The devoted gadget is still more hassle-free for rapidly linking to hotel networks and sharing web gain access to with several gadgets. The Raspberry Pi uses a various sort of versatility. I can configure it to carry out particular networking jobs, incorporate it with my existing homelab, and explore Tailscale functions without being limited to the abilities of a supplier’s firmware.
There are a couple of hardware constraints to think about, too. The Raspberry Pi’s networking efficiency depends upon its design, cordless setup, and offered user interfaces. I currently had a Wi-Fi adapter, so this was not a concern for me. Purchasing all the required parts particularly to construct a travel router might make this a more costly alternative than buying a devoted gadget. Still, if you currently own a Raspberry Pi and delight in try out Linux networking, this is a rewarding task.
