Weird behaviour.
A couple of days ago I installed another DSL router.
During the process I have somehow caused the default gw route to
disappear - on system start up the interface comes up fine, I can see
and connect to the local subnet but not to the internet.
[rkampen@timsws network-scripts]$ route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref
Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
link-local * 255.255.0.0 U 1002 0 0 eth0
is what I get at startup.
I need to add
sudo route add default gw 192.168.1.1
to get things working properly.

Google shows me a number of responses that all tell me to add a line
to /etc/sysconfig/network
which I already had.
[rkampen@timsws network-scripts]$ cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=timsws
GATEWAY=192.168.1.1
and
[rkampen@timsws network-scripts]$ cat
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
NM_CONTROLLED="yes"
ONBOOT=yes
TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=no
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03
HWADDR=00:24:8C:80:0B:15
PEERDNS=yes
PEERROUTES=yes
LAST_CONNECT=1389583930
So what am I missing?
Thanks to those that responded.
Turns out that having defroute=no is the problem - really helps to
actually read what is in the ifcfg-eth0 file.
On a side note - the various ADSL broadband routers supplied by the NZ
telcos all seem to have missing or broken bits - the vodafone one
doesn't open the firewall properly for incoming http - the telecom
device allows one to specify a different IP address for the router but
not the gw address - thus it only works if you use their default IP/gw
address. So many hours wasted.
BTW - all other devices are working just fine - just my main CentOS
6.5 WS fails.
TIA
