It doesn't seem you could. RouterOS supports a few different actions for logs, the interesting ones in your case are disk and remote.
The disk action needs disk mapped in RouterOS and that's generally only possible for local disks, e.g. if disk is USB. Not an option in your case as RB4011 doesn't have USB port.
The remote expects target to offer syslog service ... but your NAS doesn't seem to offer that service.
