If you have ssh access to the machine that will run the server, follow the next steps:
1) In the machine that you will run the server, execute:
jupyter notebook # To start the server with the default port forwarding (8888)
2) Take note of the notebook address: that will be shown to you in the terminal: http://localhost:8888/?token=<A_LONG_STRING_OF_NUMBERS_AND_LETTERS>
3) In the client machine, with remote access to the server:
ssh -N -L localhost:8888:localhost:8888 <server_username>@<server_ip>
4) Now, open the browser to use the following address: http://localhost:8888/?token=<THE_TOKEN>
Additional info (found here): It is possible to change the port on which the server is setup
# In the server
jupyter notebook --no-browser --port=8889
# In the client
ssh -N -L localhost:8888:localhost:8889 <server_username>@<server_ip>
