PAY ATTENTION: This source is coded for only personal use on
your own router Cisco. Don't hack around.
Special thanks to:
Khlero with your patience this code is out there :*
Shen139, without you I can't live :D
people that helped betatesting this code :)
Alex Kah and his Cisco Router :)
I love U all :*
