Network Drive Access

[thomasgtsr]

I am having difficulty access my network drive. I am able to access it from my office's wifi, but if I switch to our router or phone's internet connection it says it cannot find the network drive. Is the network drive name the same on any internet connection? Do I have to do anything special to be able to access this network drive from anywhere? I am pretty new at this.

Also if I need to do port forwarding, is there a way to find out which port to forward. I can access the drive on the other wireless network so is there anyway I can look it up from there.
