Forwarding SSH is a very common practice for those who have limited access to Public IPs to their home network. It is possible to enable reverse proxy other ports/services inside the same network as the remote unit is.
For example, I have a Raspberry Pi running at my local network
192.168.1.0/24. So I ran the following command inside the Pi to expose my router's control panel at
ssh -N -R 8080:192.168.1.1:80 email@example.com
