WireGuard on OpenWRT based GL.iNET: some notes on the `wireguard_watchdog` script

Posted by jpluimers on 2026/01/15

On OpenWRT GL.iNET based devices, the WireGuard client does not restart upon reboot, even if it was started before rebooting.

Hopefully the /usr/bin/wireguard_watchdog script will help with this as others indicates it should.

My first try was no succes, but since it is supposed to run from cron it does no output. The script on GL-SFT1200 firmware version 3.215, script /usr/bin/wireguard_watchdog is different from the one in the OpenWRT repository, so it needs some investigation.

Some links for checking this out:

Some WireGuard console tricks that helped me figure out a GL.iNET “status yellow” connection problem

Posted by jpluimers on 2026/01/14

TL;DR: the connection problem was because of a public key mismatch between the pfSense central location and GL.iNET peer.

Since the pfSense cannot export configuration in either text or QR format (see rcmcdonald91/pfSense-pkg-WireGuard: This is a port of the original WireGuard UI bits as implemented by Netgate in pfSense 2.5.0 to a package suitable for rapid iteration and more frequent updating on future releases of pfSense.), I made a copy paste mistake.

This resulted in the WireGuard client connection indicator on the GL.iNET to turn yellow instead of green. This means that the handshake is only partially completed (there is a WireGuard connection but there is no returning traffic on it).

GL.iNET VPN status explanation:

  • no color: no VPN
  • yellow: VPN not fully established
  • green: VPN established

Product Comparison – GL.iNet and their products I have

Posted by jpluimers on 2026/01/05

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.

Some notes on getting OpenVPN LAN2LAN VPN working from a GL.iNET GL-SFT1200 AC1200 Travel Router to a pfSense that is behind a Fritz!Box 7490

Posted by jpluimers on 2025/12/19

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):

GL.iNet 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

Posted by jpluimers on 2025/12/09

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)

connection method

Two physical drawbacks likely due to the portable nature:

  1. 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
  2. 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!):
