    Hi everyone;

    Having a problem with my ISPConfig server. I am traveling in India for the next 6 months and I moved my physical server to my sons house. Since my son has a class A network, I changed my settings from 192.168.x.x to 10.x.x.x.

    I can ssh into the server from the local area network, however the server can't reach the internet.

    [root@server1 ~]# ping -c 3 www.google.com
    connect: Network is unreachable

    Here is the output of a couple of relevant files:

    [root@server1 ~]# ifconfig

    Does anyone have any suggestions what is wrong?

    Thanks

    Can you ping IP addresses, e.g.:
    Code:
    ping -c4 74.125.77.99
    ?
    If so, you should try another nameserver in /etc/resolv.conf, for example 8.8.8.8 (Google nameserver).

    Hi falko,

    Sorry for the slow response, traveling in India, get access to the net can be problematic over here.

    Couldn't ping any external address. However, after doing some more research, I found the suggestion of adding GATEWAY= to /etc/sysconfig/network-scripts/ifcfg-eth0

    # Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]
    DEVICE=eth0
    BOOTPROTO=static
    BROADCAST=10.0.x.x
    IPADDR=10.0.x.x
    NETMASK=255.255.255.0
    NETWORK=10.0.x.x
    GATEWAY=10.0.x.x
    ONBOOT=yes
    HWADDR=08:00:27:c6:1d:54

    Seems to be working fine now.
