GL.iNET routers with dtd port?

Hello all,

I like my little GL-AR300M16 device and use it a lot for remote access. It's great that it is tiny and usb powered so easy to deploy. It has only two ethernet ports, one WAN and one LAN.port. So far as I can see, the only VLAN1 possibility is to make a mesh radio configuration and connect over rf to another rf node. As this model is 2ghz only, and our mesh network is 5ghz this is nearly impossible to accomplish ... besides the GL-iNET being a tiny radio.

What I want to do is have an ethernet port dtd to directly connect my node to a site. On a hAP ac lite this would be port 5. On a hAP ac2/3 you can re-direct ports to do what you need although port 5 is default configured for dtd VLAN1.

Is there a model of GL-iNET devices (or similar I'm not aware of) that have already a dtd ethernet port available when flashed, or that can be re-assigned similar to the hAP ac2/3? I could always use a hAP but that requires more space and more power to run.

Thanks,
Ed

I have 2 GL-AR300M16 devices and used them for remote access.

Hi, Ed:

With AREDN firmware:
The port that is not WAN is both LAN (untagged) and DtD (tagged VLAN2).
I have a GL-AR300M16 device DtD connected to my AREDN VLAN switch via
its LAN/DtD port.
It has no WAN port connection and no internet access.

It is on the 'world aredn map': http://nc8q-r2h3.local.mesh/a/status

This device has two functions:

Provide AREDN network access via 2.4 GHz to the VoIP phone by the recliner in the living room.
The phone by the recliner is also a GL-AR300M16 on 2.4 GHz.
Check for a tunnel neighbor that has 'Mesh to WAN' enabled.

The GL-AR750 has a separate

The GL-AR750 has a separate physical port for DtD. It has three physical ports. I do recall that it is no longer made however. You may find a used one that someone is willing to part with.

I use a $10 Cudy 5 port switch

I use a Cudy GS105D 5 port switch ($9.99 at Amazon) for DtD connections between 4 Aredn nodes (port 5) here in my radio room (2ac Lites, an ac2 and an ac3). The ac2 and 3 are tunnel servers (Starlink and TDS). The switch runs on 5VDC just like my GL-iNet AR300M16 except with a barrel connector rather than USB micro. The switch is very light and small, like a deck of cards. Right now I have the Shadow connected to the Cudy switch via its LAN port and it is generating a 2G Wifi access point. I'm logged into the Shadow on my iphone and can see the local 5 node network and, beyond that, the rest of our mesh. I've had the Cudy in place for about a year now, no problems.

Normally, I use the Shadow as a very portable tunnel access point. I have the Shadow tether to my iPhone's internet hotspot, and with the internet, it tunnels into the larger mesh from anywhere with cell service. I then use the LAN port for computer/tablet access to the mesh.

I may not completely understand your setup, so this may not be relevant, but I thought I would give it a try.

Awesome, just the info I was

Awesome, just the info I was looking for. I also have a small cheap switch or two which come in handy. The question was focused around the router capability of the tiny node. One thing I've found is that it's hard to move attached services around from site to site, the hostname/ip info has to be re-established every move from one router to another. Lately I've been keeping some servers with services paired to their own router, having a very small and portable router (and low cost) to add to each group of devices makes things easier. Or so it seems ....

PS ... is it technically possible that the WAN port could be re-programmed to be another LAN/VLAN1 port? That would be awesome for emergency use when there is no WAN to deal with. If yes, I will put a request into github for a new feature.

Some can, most can not.

Some devices can do that - most can not. It depends on the hardware capability. For example on the hAPac3, you can assign the ports.

GL-AR300M16-Ext

Trying to set up a 300 and after I load via local upgrade like I did my last one it gives me a failed checksum message when it tries to upgrade.
I tried to go back several versions and get same response.

Any suggestions

There is a way to force the upgrade, but it's not easy to find.

Hi, I hope this is relevant. Check post #22 in this thread GL-iNet B1300 Firmware rejected | Amateur Radio Emergency Data Network There is a way to force the upgrade that I have had to use a few times. This thread #22 has a step-by-step guide.

It is also mentioned here GL-iNet AR300M16 firmware verification fails, over and over again | Amateur Radio Emergency Data Network but with less detail.

Here are some screen shots with before and after. Also Tried two different versions. Just saw message on possible solution will give a try next and report but for now.
