Hope someone can help. I'm running vtserver -p 50000 on a remote machine (bambu) which is behind a firewall (ssh.ac.uma.es). Locally I've create a tunnel with ssh: ssh -L 50000:bambu.ac.uma.es:50000 ssh.ac.uma.es. Then, locally I've my vtlec configured to use localhost as the remote machine.
So, when running the activity it's connect and run at the beginning, but then, in the remote machine I can see that the vtserver tries to open two other ports (different from the 50000 one) but it can not due to the firewall. I can not create a tunnel for these two other ports because they change from one run to the next.
Thank you very much in advance for any help.
