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!):

LAN/WAN network building: test and know how to locate your cabling

Posted by jpluimers on 2025/09/04

I have seen too many sites where cabling was laid en never tested before actual use, which meant locating the cabling and faults was a nightmare.

Be sure to have good (which can be very simple, but more complex when Power over Ethernet is involved) testing hardware and use it during installation. You will thank yourself later.

A few videos that can be helpful:

If I have not found pfSense hardware by now: Gowin R86S mini PC offers 2.5GbE and 10GbE networking for $310 and up – CNX Software

Posted by jpluimers on 2025/08/15

I have been contemplating on pfSense hardware as there has been a large shortage on that market especially for having more than 2 ports (similar to for instance Mikrotik PoE router unavailability).

If by now I have not found any, I might want to revisit [Wayback/Archive] Gowin R86S mini PC offers 2.5GbE and 10GbE networking for $310 and up – CNX Software has 3 RJ45 ports and 2 SFP+ cages.

They found it via this 4 page review:

In case I need a small 5-port managed switch that can do port-mirroring: GS305E | Easy Smart Managed Essentials Switch | NETGEAR Support

Posted by jpluimers on 2025/08/13

[Wayback/Archive] GS305E | Easy Smart Managed Essentials Switch | NETGEAR Support which can do many-to-one port mirroring.

This is a newer and cheaper hardware revision than the:

  • GS105Ev2 (which is managed and can do port-mirroring, and is confusingly sold as GS105E-200) which in Germany already is end-of-life
  • GS105Ev1 (which is unmanaged and cannot do port-mirroring and is confusingly sold as GS105E-100) which is end-of-life but still sold

Via [Wayback/Archive] Everyone Should Have One of These – EASY Packet Capture! – YouTube who explains very well why you need a switch that can do port-mirroring, then recommends the GS105E but forgets to mention:

  • there are different revisions of the GS105E with the above drawbacks
  • there is GS305E

H3/H2 Net Card – ODROID – wonder how well pfSense supports it

Posted by jpluimers on 2025/04/18

I wonder how well [Wayback/Archive] H3/H2 Net Card – ODROID is supported by pfSense. It is an M.2 based PCIe network card that adds 4 ethernet ports of 2.5 gigabit each to an ODROID H2 or H3 series (so you have 6 ports total), ideal for some hefty router.

Pictures (from the above link) of the board, cases and mainboard below.

But first: Realtek NICs is not vendor supported on FreeBSD (which pfSense and OPNsense are based on).

How to send raw network packets in Python with tun/tap

Posted by jpluimers on 2025/02/20

For my link archive: [Wayback/Archive] How to send raw network packets in Python with tun/tap

I never really played around with tun and tap, so this is a nice opportunity to do so. I know they were the base for VPN on Linux, but just now I learned TUN/TAP are not available on nx, but also on Windows. Cool!
