My book live on different ip

Here is my situation.

I have a MY BOOK LIVE 3TB connected to my router that suddenly cannot get Remote Access.

WD Support ask me to Quick reset the MBL but to do so I need to buy another HDD to move all files.

I tried to the SSH reset but did not solved the problem.

I found a solution connecting the MBL directly to the modem but now I have the MBL on ip 192.168.1.xx and all my devices (through the router) on ip 192.168.0.xx

Is there a way to let all devices “see” the MBL on different ip?

If you press the reset button on the back side for 4 seconds, it wont delete your files, it will just restore the configuration back to default. Once you press the reset button the router should assign a new IP number.
