Wake for network access on battery power?

Hello there,

For the sake of running an SFTP and ssh server on my local network, I would like to have "wake for network access" or "wake on lan" enabled on battery power for my mid-2012, 13" MacBook pro. I tried finding out how to do this on my own but to no avail. The terminal commands "sudo pmset -b womp 1" and "sudo pmset -b force womp 1" didn't work either. If anyone could help me achieve this effect, I would be very grateful.

Thanks,
