Everytime when installing a pfSense router from scratch, I seem to re-learn a few of the below quirks. So it was finally time to document them (:
Quite a few of my pfSense configurations are just doing routing between various networks, should not provide DHCP leases and do not always need or have a WAN connected (i.e. they are LAN-only).

At the time of writing (during the Covid-19 Pandemic) the [Wayback/Archive] Product Comparison – GL.iNet contains the below products.
I got 3 of them (2 are variations of the same model) and their quality/price ratio is great, even with the prices that risen during the 2020-onwards global chip shortage.

TL;DR: avoid Digitus AC fans, but use DC case fans with built-in/external temperature controller plus 12V or USB-step-up power supply and optionally fan grilles/meshes.
A while ago, I bought a 7U shallow 19-inch rack cabinet to house some of our network equipment for the offices and other rooms at the top floor: [Wayback/Archive] DIGITUS Professional Network Wall Housing – Soho Wall Cabinet: Amazon.de: Computer & Accessories
Since it was to be mounted in the boiler room, which is on the top floor under a flat roof, it would get warm so I wanted fans installed in it under or over the air vents in the housing (the cabinet is delivered as flat-pack with parts pictured below and requires about half an hour assembly time):

TL;DR: it failed
Since GL.iNET does not support site-to-site “Peer to Peer” OpenVPN (only “Remote Access” is supported) which is needed to route to/from the networks on both sides of the connection. the below did fail.
Original idea
Below was what I hoped to function.
Some links that should get me started (though my situation is a tad more difficult, see below):

For my link archive a router I bought a few years back: [Wayback/Archive] GL-SFT1200 Secure Wi-Fi Router On The Go – AC1200 Dual-Band Gigabit Wireless Internet Router | IPv6 | USB 2.0 | MU-MIMO | 128MB RAM | Repeater Bridge | Access Point-M Mode: Amazon.de: Computer & Accessories
- It is USB-C powered (the power brick delivers 3A at 5V, but in reality it uses far less).
- Mode and reset buttons are behind the antenna (see picture below).
- It is specced as AC1200, but that’s just theoretical a number.
- It came with EU and UK plug.
I needed it because from prior experience, I knew GL.iNEt can support a special Wireless Repeater mode where it still functions as a router (hiding the LAN/WLAN behind NAT)

Two physical drawbacks likely due to the portable nature:
the plastic RJ45 ports are slightly too wide which means that these keep falling out [Wayback/Archive] Inline® Dust cover, for RJ45 socket, color: green, 100pcs. Pack: Amazon.de: Electronics & Photo
- no holes in the base to hang it to a wall
One firmware drawback: it shipped with v3.212 for which I could not find release notes. Luckily the firmware v3.215 I upgraded to had: [Wayback/Archive] Firmware v3.215 is released – Technical Support – GL.iNet.
Links to product and manuals (the paper manual are just two thin sheets, but the on-line documentation is OK; I was surprised WireGuard and Tor were supported!):

Besides the August 2025 XKCD infrastructure dependency inspired cartoon on the right, the more recent and great [Wayback/Archive] XCKD: Dependency derivative below is a monumental piece as it combines the recent:
- fiber outage of the Internet Archive
- DoS of Cloudflare by itself
- AWS us-east-1 dependencies outage
- Crowdstrike DoS of Windows machines
- framework-du-jour mentality in the JavaScript world
- many more¹

On my list of hardware/software to experiment with is [Wayback/Archive] Meshtastic:
An open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices
Via [Wayback/Archive] @jilles_com@infosec.exchange on Twitter: “Will be taking to meshtastic.org Lora 433MHz modules to @hotelhacker. Might be cool if more people could bring some to setup a larger mesh and play with them. amzn.eu/d/aCgULy4“
Products:
For both boards, this holds:
1. The Meshtastic program is not pre-installed on this product. If you need to install, please check the steps:
github.com/geeksville/Meshtastic-Android/blob/master/README.md
github.com/meshtastic/meshtastic-device/releases
2. If GPS does not work, the following situations may occur:
Install the Meshtastic firmware before and now reset the GPS when you switch to another firmware.
Reset steps: github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series/tree/master/firmware/GPS_%20reset_test
3. If GPS is weak indoors, it can be used outdoors
4. The GPS antenna is not installed stably, you can check if the interface is attached to the GPS antenna
