How do I open up my Mac to remote sharing anywhere?
Solution 1:
I would recommend the screens app and screens connect. The software is not only fast and works excellently, but it helps diagnose if your network conditions are not correct to accept incoming traffic past any firewalls or NAT borders.

For ssh, I use prompt and recommend that as well.

Together they solve all issues like not knowing your IP address of your router or having to set up dynamic DNS.
Solution 2:
A contrarian approach to bmike's answer would be to utilize a Dynamic DNS (DDNS) to give you DNS services to your dynamically assigned IP address. You will need to configure your firewall to allow/forward ports as necessary, but on the flip side, it gives you far more options (like hosting your own web servers)
Dynamic DNS
There are many DDNS providers; some paid, some free. I personally recommend FreeDNS as they are free (as in beer) and compatible with a number of routers and virtually all operating systems.
Basically, you'll register on their site by selecting a TLD and then adding your host info. For example: myhost.example.com They''l assign you to example.com but you can choose the name of your host (myhost). From there, anywhere on the web you can reach your home by going to myhost.example.com.
Firewall/Port Forwarding
You can forward all traffic from port 22 (SSH) from the router directly to your server. In fact, your can use a non-standard port (i.e. 40022) on the firewall for added security. When you SSH, you just specify the port and the firewall will forward it appropriately.
ssh [email protected] -p 400222
The same hold true for SCP and SFTP as well. You'll need to consult your router's setup guide for specifics on port forwarding.
There are a number of clients available that work on routers or on the system. If your router supports it, use that client. If not, install the client on your server and have it update periodically.
Solution 3:
Why not just utilize iCloud Drive? Once you have it set up correctly in System Preferences, any of your computers... including your iPhone, which are logged into your iCloud account, have access to all of the same files on your iCloud drive (which can be accessed at https://www.icloud.com/ using a web browser or in Finder.app)
