Proxy server?

[whosrdaddy]

I use the Duet via a static IP and port forwarding without any issues..

[dc42]

The Duet WiFi with firmware 1.18.2 and earlier don't allow a static IP or gateway address to be configured, but 1.19 firmware does. So it may be that port forwarding already works if you use 1.19 firmware.

I have used Port forwarding on my Duet WiFi without fixing the IP Address by locking it to the same IP in the router and then port forwarding to it it worked for me at the time.

Thanks so much.
I'm no I.T. expert by any means but I had wondered if the current firmware's lack of ability to configure a static ip was a factor.

Do you think the current beta is worth a try or should I wait for the next release?

Doug, this is exactly how I have mine configured but I haven't had any luck.

UPDATE:

I figured out why I couldn't connect to the Duet remotely.
I did not have Telnet enabled in my settings on the router.

I remember enabling it when I first set things up, but before trying to connect to the duet, my router notified me that I had a firmware update while I was logged into the portal. I guess when the new firmware installed it set those particular admin settings back to default, and I didn't think to check it.

I am in business!

Thanks to all who responded.

Disregard that….

I got all excited for nothing. I wasn't paying attention and I had my wifi enabled on my tablet when I tried to connect, so I was still in sidemy local network. I disconnected from the wifi and used the cell data and no joy.

Back to the drawing board.

[Dougal1957]

Try setting the port forwarding to be the DMZ in the router and don't forget to specify the correct port which I believe is the std 80

Yeah, IP forwarding should work fine. However, exposing it without proper authentication means anyone can control your printer, so it's probably not a great idea. That's why I use a reverse proxy that adds HTTP authentication.

[Scottbg1]

Doug,
Thanks for the suggestion. I tried applying the DMZ to the forwarded port but still no luck.

FWIW, I went ahead and bought a Raspberry Pi and installed Octoprint on it. It only took me about 5 minutes to get it connected outside of my network. I only mention this because if others have had luck connecting the Duet, then maybe it was my Router. But being able to connect the Raspi leads me to believe that it is a setting in my Duet's configuration.

BTW, I am impressed with Octoprint, but I still prefer DWC over it any day even though I wish it had a couple of features that Octoprint has. If can I get the Duet to connect, I will use the Raspi on a separate ip to connect a streaming camera.

I am going to try the Beta firmware that David mentioned. Maybe being able to assign a static ip on that end will fix the problem.
I have just never been a fan of being a beta tester so I have held off on trying it.

[Scottbg1]

Installed v1.19 firmware.

It works now but….

I have to have wifi enabled on my phone to connect to the DWC. Once it's connected I can turn wifi off and control everything over the data connection. I can disconnect and reconnect, everything. But If I close the browser and then navigate to the IP just using the data connection, it hangs and won't connect.

This is so strange as I can connect to the raspberry pi/octoprint server straight away with no issues.

I'm baffled.

i'm having the same issue here and i need to solve it too!!!

All this really depends on your router and has little to do with the Duet…. Depending on your router Asus or any router running firmwares like OpenWRT should support two different functions

1. You should be able to configure a static IP address via the DHCP configuration page, using the DuetWifi's MAC address or any other IP connected device for that matter

2. Port forwarding, once you setup the assigned IP address then you need to configure port forwarding to forward port 80 from your internet IP to your DuetWifi IP that you configured in the last step.

3. Asus routers and others support reverse DNS services, even if your router does not support it, there are services that can be signed up for that do which gives you an easy way to connect to your home IP address via a url like: http://mynetwork.asus.com

Tape,

I was able to connect to DWC once I upgraded to 1.19. SO that was fixed.
But I never figured out why my phone wouldn't connect straight away.
I don't think it's a DWC problem but maybe a security thing over my network.
When I try to connect over data, I think my firewall doesn't recognize that connection as a secure one.
I can connect via wifi anywhere that I can connect to wifi and it loads fine.
I just connect, and get it working and leave that tab open in my phone's browser because once I am connected, it will stay connected with data only until I close the browser, or I have to power down the Duet for any reason.

Btw, it's worth mentioning that I power my printer with an ATX PSU and I employ the option the Duet offers to power down to a low power state instead of completely off. So Even though my printer is off, I can still connect to DWC.

I hope this helps.

i have the port 80 open and forward to the ip 192.168.1.90 but i cant connect from the outside, only inside the network.
but if i connect inside the network via wifi and then disconnect wifi (still connected by 4G), i'm still able to control the duet.
i have an arduino Yun and i can control it from the outside with no problems at all!!!

Then you're describing the same situation that I mentioned above.

I just connect when I'm around wifi, and leave that tab open. If I want to search for something I just open another tab and leave the Duet tab in the background. Or I just find a PC that I can connect from, which in my case is usually my work PC.

[tape]

Yes exactly the same.
