I'd like to share a disk to a Mac on the WAN using the
smb protocol. To share the same disk over
afp, I simply forwarded port 548 to be available to the WAN. For
smb, I've tried forwarding every port that seems to be related, but am unable to mount the disk.
Please answer if you are able to forward access to your disk to another network, and the steps you took to do it. Maybe it's more than forwarding ports.
