I have strange issue with OMV installed in my raspberry Pi 3B+. I have setup a static IP 192.168.1.50 through Network->Interfaces page and it works fine. Problem starts if I reboot my Fiber Optic DBC Router, it then gives a different IP eg 192.168.1.2-255 to my Raspberry Pi. But once I reboot my Pi it gets the static IP back. If this happens I am unable to access my Pi if I am outside and my router reboots after a Power Cut. is there any other solution where I can give a static IP to my Raspberry Pi. When I try to do it through dhcpcd it does not exist in Openmediavault.
