Tunnel Gre problem between two hosts (vps and dedicated server)

[AleDevite]

192.168.*.* is a local or intrAnet (not intErtnet) address issued from your router. Is not a server public address except on a local network. Somewhere in your PC client configuration (not your router other than port designation) you must connect actual public server addresses. You will need server public address somewhere when you are doing inter-country connections. That aside maybe I misunderstand your question. Below is a somewhat informative link for setting up the tunnel. Cisco should also have helpful information on this subject.

I've also tried this internal IP 10.10.10.1/24 and 10.10.10.2/24 but nothing.

I'm using the same guide you sent: https://wiki.buyvm.net/doku.php/gre_tunnel
