Enable port forwarding because my server is behing router with the firewall enabled. So I need to open some ports to have access throught internet. The ports that I opened is for ssh and vnc.

Click on linux_24n5.

Assign a new application to my server. You can see here that it has a static IP address.

Create a new rule beacause I have changed the default port that ssh plays ;)

Add new port that I want to forward.

Assign the new rule to my server.

Opened another one port for VNC.

Connect with VNC using a public IP. Port forwading is working succesfull.

Connect via ssh using public IP.
