Hello,
I write this topic today as I have successfully installed my Raspberry Pi on my Co2 laser, with RuiDa controller on it, and Lightburn bridge software. I’m using an Acer Predator, running Windows 11.
My problem is that when I’m connected to my distant server (Windows VPN, for work), Lightburn bridge doesn’t work. When I disconnect the VPN, everything works fine.
I already modified my VPN settings to use my local network for internet connection, so it’s just to transfer and get my files from this server.
Can you describe your network topology? Specifically, are you connected to LB Bridge with the same network card and IP that you use to connect to the internet?
Can you elaborate on this? Have you allowed local networking while on VPN? If so, are you able to connect to other local network resources? If not, you’ll need to allow for this otherwise there is no chance this will ever work.
What specific VPN software and protocol are you using?
It’s a L2TP protocole created directly on Windows. I unchecked the “Use default gateway on remote network” box in my IPV4/IPV6 advanced settings to use my local internet connection while using my VPN access. (as mentionned in this step-by-step process: Accessing Local Network Resources While Using VPN - Spiceworks)
I verified, and that’s correct, I’m using my local network connection. What do you mean by “other local network resources” ? I don’t have other things connected on my local network to check this, and I’m not really skilled in “computer science” things.
Once you can confirm your IP addresses that will be helpful.
There are a few things going on in the VPNed view that are interesting for me.
Do you know what the 192.168.1.219 address is?
There is a 192.18.0.1 address as Gateway (Adr. passerelle). Do you know where this came from?
I didn’t realize you’d have a public IP in the list. You may want to edit this post and blur-out the address on the first column fifth row of the screenshot.
When you have a chance, can you try pinging the IP address of the Bridge from your computer while connected to VPN? Try running these commands in Command Prompt:
Hello,
My PC ip is: 192.168.1.21
Bridge ip is: 192.168.1.131
I don’t know, maybe my wife’s phone… I don’t know. EDIT: It’s my distant server, as I tested ping this IP with and without VPN activated.
I don’t know neither. EDIT: As mentionned at the last screenshot of this post, it seems to be the distant server as well. On my first screenshots, you can see that 192.168.1.219 and 192.18.0.1 are the same thing.
Thank you, I hope I hide the correct ones
While not connected to VPN:
While connected to VPN: Failed. 100% lost, and then, there is 192.18.0.1, you asked about back at point 2. , appearing, so it’s probably the distant server ip?!
I think the reason you got this was because the new route is permanent. So the second time you did it there was already a route added so gave you the error message.
I re-enabled the “Use default gateway on remote network” and it works. Both commands and connexion with my bridge. But the reason I unchecked that “Use default gateway on remote network” is that I need to use my own local network to surf on internet, instead of using the distant connexion for that, even when my vpn is on.
Edit: After your suggestion. I unchecked again the “Use default gateway on remote network” and checked the checkbox just under this one, it’s “disable class based route addition”. And now I’m still connected on my local network for internet and Lightburn find my bridge directly, but I can’t have access to my distant server with this option.
Ah, I didn’t realize you wanted to bypass the vpn for internet requests as well.
This is because the necessary routes for the VPN are not automatically added with that optoin. You will need to add these manually in that case.
Can you do this? Uncheck “Use default gateway on remote network”, uncheck “disable class based route addition”. Then run this command and direct message me the results. Don’t post here.
