I purchased one of these in a bundle of hardware, checking the website, I did not see anything about the OS limitations on the hardware info page, I had to open up the manual to see that it only ran on Linux, and not even all flavors, can anyone tell me if it works with Debian Linux, FreeBSD, or ESXi 7? searching the forum hasn’t been fruitful
User manual says any Linux having kernel 5.15.25 or RouterOS7, not Windows.

If you really want to be sure, best to ask Support.
