SSH/SFTP from outside to my Mac

[Kilamite]

I have a Raspberry Pi and a Mac with SSH enabled. I want to SSH to my Mac from outside, however having trouble differentiating between my Mac and Raspberry Pi.

If I SSH from the outside using my public IP, my router always relays that onto the Raspberry Pi. I can then tunnel from the Pi to my Mac, but that isn't ideal when I want to SFTP.

I've tried opening up additional ports on my router, one for my Mac's LAN IP and one for the Pi, and SSH using those ports to differentiate between my Mac and Pi but no luck.

Worth mentioning that even with the Pi turned off, I can't SSH to my Mac from the outside.
