    I have one question:

    how come that when i use command:
    netcat -vz localhost 1212
    i get
    Connection to localhost 1212 port [tcp/lupa] succeeded!
    and when i use

    netcat -vz 1212
    i get
    netcat: connect to port 1212 (tcp) failed: Connection refused is my IP number of my server

    So why this both dont work and my ISP have port open plus i have disable firewall and i use opensuse 13.1 on my server

    on your router, is the port actually forwarded to the right local machine?

    My server dont have router, plus ISP dont block any port and
    firewall i disabled. I am thinking if there is anythink else
    if ISP can block port?
