I have a WRTG54G V5 router for my Comcast Broadband service with my home PC connected directly to it. I have forwarded port 3389 to allow a Remote Desktop Connection from my PC at work to my PC at home. This works fine, but I would instead like to simply access the files on my home PC via a mapped network drive. I tried to forward ports 137-139 and 445, but that doesn't work when I try to map the drive at work. Anyone know how I can set this up? Thanks for the help.
