Then, when you are away from home, connect to your external IP address and the router at home will forward that request to your computer and you’ll be connected.

Why is ssh port forwarding for remote devices behind firewall?

Often that makes sense as they operate an open web server on port 80 (http) or they have a low security web application setup with only basic login. Therefore these devices are isolated from the outside by firewall and NAT.

Where does the SSH server send the traffic to?

When you attempt to access the database server at port 8888 on your current PC, the traffic will be sent over the SSH connection. When it arrives on the system running the SSH server, the SSH server will send it to port 1234 on “localhost”, which is the same PC running the SSH server itself.
