To do a wol from pfsense, just click the little button in the dhcp leases ;) Which will add that mac to your wol table..

Not sure why anyone would want to have their nas in standby in the first place ;) Mine is doing all kinds of stuff in the background during "off" hours.. Creating plex video previews, maint on plex, etc.
Never know when someone going to watch a movie at 3 am as well, etc.
There is also normal other maint that synology goes through off hours, backups, reports, etc.
