Hello, because of some reason,i have to change my server IP address which already build i followed this tutorial http://www.howtoforge.com/perfect-s...hp-mysql-pureftpd-bind-dovecot-ispconfig-3-p2 before i change my IP addres, my server working fine but after i change my IP address, my server cannot acces from the internet Where is my mistake ? Thanks for any advice
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 for example 103.xxx.xxx.xxx/webmail if i type that addres from browser, anywhere, i can acces my roundcube webmail but after i change my ip address, i can not acces it anymore my new ip addres is 10.xxx.xxx.xxx can you help me ?
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?
i can acces internet from my server but i dont know my ip is under router or not ? sorry if i can explain about that
This IP is set directly to the server? Post the content of /etc/network/interfaces You can mask the IP's inside
Yes the ip set to server this is the screenshot file:///home/istrator/Pictures/Screenshot%20from%202014-10-16%2018:55:19.png
sorry if the image can't see this the /etc/network/interfaces content # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 10.120.21.100 netmask 255.255.255.0 network 10.120.21.0 broadcast 10.120.21.255 gateway 10.120.21.1 dns-nameservers 10.120.21 8.8.8.8 8.8.4.4
Dude, 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.
