Port Forwarding

Hi @nviennot @juniorz @oscarh @ebardie @gee-forr @starlilyth @varac

I have used tmate as terminal sharing, and that is really great!

Here is my scenario:
I have installed tmate server on with a public IP server (VPS) using:
docker run -d --name="tmate-server" --cap-add SYS_ADMIN -v $(pwd)/keys:/keys -e SSH_KEYS_PATH=/keys -p 2223:2223 -e SSH_PORT_LISTEN=2223 -e SSH_HOSTNAME=persl.ddns.net -e USE_PROXY_PROTOCOL=0 tmate/tmate-ssh-server:prod
and the Client 1 [Ubuntu PC with GPU] connects to the tmate server to get an ssh key address to share with the client 2 [ windows PC]
Note: Client 1 [ubuntu] does not have public Ip address to connect Directly! (modem is not accessible)

                                |----------------------| 
                                |      Tmate Server    |
                                |----------------------|
                                          | |
                           ---------                    -------------
                 | |                                                  | |

    |----------------------|                                 |---------------------|
    |    MY ubuntu PC      |                                 |      Windows PC     |
    |     (has GPU)        |                                 |    (client of ssh)  |
    |----------------------|                                 |---------------------|
    

Its all good till now. But the Ubuntu PC is used for deep learning tasks and i want to share the notebook with the Windows PC!

in the ubuntu PC, Jupyter Notebook is installed which exposes port 8888 on all the Ip addressese (0.0.0.0) to be able to open a web interface ( like webpage ) on port 8888!

How can i share this notebook with the windows PC to be able to use the available GPU of Ubuntu PC?
I have tested

ssh -p2223 -L 8888:localhost:8888 [email protected]

and Also tested with -D
but none of them worked for me!

Is there any configurations that i'm missing? in ssh or tmate?

I would appritiate any kind of help in this regards/:

Thanks
best regards
