your default gateway is not set correctly.

the ip address of your nic is set as your default gateway.
the default gateway ip address should be your router/modem/whatever.

your internet access is working because your gateway is smarter than you are.

to the file /etc/sysconfig/network add the line:
    GATEWAY=192.168.195.xx
where 192.168.195.xx is the ip address of your gateway. then:
    service network restart
