Trainer on remote server

[LJS1]

Hi,

I'm trying to setup the trainer on a remote server that does not have direct internet access, but can be accessed via a gateway server. I have setup a tunnel via this gateway and added a LocalForward from port 55557 (trainer) on localhost to the same port on this remote server.

From SSH config

Host <servername>-tunnel
    Hostname <gateway>
    LocalForward 55557 <servername>:55557
    RemoteForward 8080 localhost:8080
    MACs <MACs>
    ExitOnForwardFailure yes
    ServerAliveInterval 60
    ServerAliveCountMax 3

When running the trainer, I get the following warning messages:

INFO:2024-05-21 10:44:36,915:Local for client: Started to connect.

I had hoped I could make another tunnel that would allow the trainer to connect to the internet via a RemoteForward and then set these variables:

export HTTP_PROXY=http://localhost:8080
export HTTPS_PROXY=http://localhost:8080

Does anyone with more knowledge have any idea how I could set this up and what I would need to change in my config.json? The TMRL config file uses the same ports as in the standard config file.
