I'm realy sorry for this message but I'm very noob and my mistake is a proof
I have made 2 IP configuration for my NAS. One static for the web interface and one dynamic in VLAN for make it accessible with my router.
I was happy with that but my NAS was invisible on my VR headset so I tried invert the one who is dynamic and the one who is static to see if it change something.
The problem : I validat with the exact same static IP for both and now I don't have the hand on the web UI and I'm too noob to know what to do on my DOS-like interface on the NAS
I'm realy desperat and hope I will not have to redo all from scratch
If anyone have any solution I would be realy greatfull
