Changed ip, internet connection problem

Hallo,

I recently installed a new server with ispconfig 3, everything worked fine. I run multiple websites with different clients and multiple mail and ftp users. But I just changed my server ip address and gateway configuration, and can’t connect to server with ftp or send/receive mail.

I think I don’t have internet connection on my linux system, what is strange because I can connect to the different websites on server and get a connection with putty. if I am logged on the server, I can’t get a connection with different aps like apt-get update,links, or wget.

This are the configurations I changed:

From:

Code:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
#allow-hotplug eth0
auto eth0
iface eth0 inet static
        address 192.168.120.120
        netmask 255.255.255.0
        network 129.168. 120.0
        broadcast 192.168. 120.255
        gateway 192.168. 120.1

        broadcast 192.168.2.255
        gateway 192.168.2.254

After that I did:

Code:

/etc/init.d/networking restart

And changed the host
From:

Code:

127.0.0.1       localhost.localdomain   localhost
192.168.120.120   LinuxServer.j2e.nl      LinuxServer

To:

Code:

127.0.0.1       localhost.localdomain   localhost
192.168.2.120   LinuxServer.j2e.nl      LinuxServer

And did:

Code:

echo LinuxServer.j2e.nl      > /etc/hostname
/etc/init.d/hostname.sh start

I hope you can help me, thanks in advance

 

did you change DNS record, or external IP was not changet?

 

I’m new to servers and Linux, i did not work with the tab DNS in ISPconfig. And yes my external ip has changed, but I don’t think that’s the problem?, I don’t have internet from inside the server..

 

can you ping, like ping google.com?

 

No i can't ping any website on wan.., i can ping in the lan.
