Correct Marshall. (Sorry guys, forgot I started this thread lol)
Yes, I have a Western Digital Raided drive plugged into the USB port of the router. (The "3" was a typo.) When I disable all security I can access it from the outside world... but so can anyone else. When I add security I cannot access it from outside through ftp.
I can explain better when it's in front of me (@ work now).
I can't be the only one with this bad boy??? It's a SWEET router. Just need to resolve this one issue.
Asus Z170X + Asus GeFroce GTX Turbo 1070 +... all kinds of Asus goodies. #Fanboi
Congrats mate, now...would you please be so kind as to list what you have done to get it working correctly? and hopefully a Mod or someone else will sticky this to show how to get it working...or, create a new thread Peregrine and that can be stickied as it is pretty important for other users to know, if they too get stuck on this exact problem.
