I've setup a VM instance following this tutorial: https://www.digitalocean.com/community/tutorials/how-to-set-up-dante-proxy-on-ubuntu-20-04
The problem is that i can't connect the service that i want using the proxy. I'm using external_ip_of_vm:port:user:pass . But the proxy doesn't seem to work. When i try to log in on the game that i want, nothing happens, but when i try to connect without proxy, it connects.
I think this can be related to the firewall setting on the GCP. But i don't know how and which rule should i create to get the proxy work.
I'm using port 1080 inside Dante Proxy, as the tutorial. Thanks to everybody who dedicated time to read and i will be thankfully if you can help me to solve this problem.
