Intel Nuc NUC6I5SYK running Linux not accessible from outside LAN

Hallo all

I do have a
Intel NUC6I5SYK | i5 | 8GB DDR4 | 128GB M.2 SSD | WiFi | Bluetooth | Windows 11 PRO

It is running Linux Mint Xfce 20.3

I cannot access the Nuc from the internet into my LAN.
Despite of proper router port forwarding, it does not accept being connected from outside my LAN.

ssh (TCP) does work inside the LAN, not from outside the LAN
motioneye (TCP x http) does work inside the LAN, not from outside the LAN

All other computers and raspberry's are reachable from outside the internet, through my router. Only my Intel Nuc NUC6I5SYK refuses.


Are there any bios / uefi settings to be changed ?
I could not find a candidate, when searching around.

Who can help ! How to investigate ?

Thanks in advance

Kind regards, Hans

Windows 11 is not supported on your NUC. 

If you are doing some sort of dual boot, you are on your own.

I did bought the NUC refurbished with windows 11 pre installed. Which works rather well. I'm running in in Linux, as mentioned in my topic ! Which runs very well. One challenge remaining ...

Someone screwed you on having Windows 11 installed.  Microsoft does not support 7th gen and lower processors on Windows 11.  There are no 6th gen processors on Microsoft's W11 supported processor list.

This is your NUC:

https://ark.intel.com/content/www/us/en/ark/products/89188/intel-nuc-kit-nuc6i5syk.html

 

It has an i5-6260U processor, thus W11 is not supported.

 

Additionally, there is no version of linux supported on your NUC:

Sorry, Linux and W11 may work, but neither are supported.  And, it is all about support.

Thanks for all the info. The Nuc does everything. except being accessible from internet through my router. What can then still be the difference with all those other pc's ? And how to judge on any other computer, i might buy ? How do I know if this will work ?

I still do believe, it has nothing to do with what ever windows version. Frankly said : I dont care about windows. And ... it even runs windows 11 without any problem, as far as i know with the bit things I played around on it. Which is easy to check, since I did install Linux multiboot with windows.

Linux is champion networking, my router is one of the most sophisticated ones. Runs all I need for several years ...

There is some setting somewhere ...

Did you configure your router to assign a fixed local IP address to the NUC and could you confirm that you have forwarded the port 22 to this address (/usr/bin/ip -br address) ?

Also, in addition to Windows 11 and Linux not being supported, your nuc is no longer supported.
