CentOS server cannot connect to external IPv4 sites

Question

I recently installed CentOS 6.5 on an old laptop I had, and I am currently using it alongside Samba as a backup server. The problem is, It cannot connect to other external services (outside my home network) using IPv4. For example, doing wget 173.194.33.129 (Google's IPv4) returns a:

[root@nas ~]# wget 173.194.33.129
--2014-11-05 06:28:48--  http://173.194.33.129/
Connecting to 173.194.33.129:80... failed: Network is unreachable.

while doing wget google.com works just fine. I am able to ssh into the server via it's internal IP address (192.168.1.xxx).

Here is my /etc/sysconfig/network-scripts/ifcfg-eth0:

DEVICE=eth0
HWADDR=B8:88:E3:35:4A:A2
TYPE=Ethernet
UUID=b063301b-a5e8-4eec-9dda-5bcba54a0163
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.1.103

Answer 1

Check your netmask. You seem to be missing both **

NETWORK=192.168.1.0

NETMASK=255.255.255.0

Try reconfiguring the NIC. Install system-config-network & use it to reconfigure the NIC.

yum install system-config-network

root@host:~# system-config-network

**(I am assuming that you are using the 192.168.1.0/24 subnet) Hope this was helpful. (^_^)
