I already tried disabling the firewall in CentOS to see if that was the problem but to no avail. The reason there are multiple instances is because there are multiple IPs configured in it, but even when specifying a single interface the result is still the same.

I've had setup my CentOS 7 box to wake up my Windows PC a couple of years ago and it was working fine, until for whatever reason it stopped working one day and I just couldn't figure out what the problem was and let it go. and that Wake On LAN is supported only for Windows guest operating systems.
