    Your question is a little bit confusing. Maybe is a DNS problem.

    You mean you cannot access it from internet via a domain name or IP?

    before i change my ip addres, i can acces my server from internet or another network,
    because i dont have any domain yet, i acces it by typing ip addres

    but after i change my ip address, i can not acces it anymore
    my new ip addres is

    OK. This IP is on a router/firewall and is a NAT to the internal IP of the server? From the server you can access the internet?

    This IP is set directly to the server? Post the content of /etc/network/interfaces

    You can mask the IP's inside

    Dude, it is a link to an internal file... it's not available for me.

    Copy/paste the information.

    Your IP looks like a LAN -IP, so you are behind a router. This IP it's given to you by your ISP? I do not think so....

    Connect to your router/firewall and make the necessary changes so the external IP of yours point to the internal IP of your server.
