How can I define my Gateway

English Network/Internet
#1

on an Opensuse 11 I have config my /etc/sysconfig/network/ifcfg-eth0 :


BOOTPROTO='none'
BROADCAST=''
ETHTOOL_OPTIONS=''
IPADDR='192.168.51.30'
MTU=''
NAME='name of my card'
NETMASK='255.255.255.0'
NETWORK='192.168.51.0'
REMOTE_IPADDR=''
STARTMODE='auto'
USERCONTROL='no'
GATEWAY='192.168.51.2'

if I run a route command I get no default route, only 192.168.51.0, link-local, and loopback.

How can I define a default route Gateway permanently.

I try
route add default gw 192.168.51.2

but when I reboot I got no route default again

thx :slight_smile:

The default gateway does not belong to an interface but is global. It is set in /etc/sysconfig/network/routes. The format is:

default *gatewayaddr* - -

Or set it with YaST … Routing

The man page for routes is very useful, type

man 5 routes

in a console to read it.

To solve your problem, edit/create the file ‘/etc/sysconfig/network/routes’

add this line: (using information from your post)

default 192.168.51.2

Either reboot {shudder} or ‘rcnetwork restart’ to have this change
implemented.

Take Care,

I don’t have a ‘/etc/sysconfig/network/routes’ file

there is all files and folders in /etc/sysconfig/network :

config
dhcp
id-down.d
if-up.d
ifcfg-eth0
ifcfg-lo
ifcfg.template
ifroute-lo
providers
scripts

Do I have to create routes files? what do I put inside?

Thx for your answers

Why not use YaST to configure your networking, then you can see what format it generates in the files?

Ken is right, YaST would be a better tool to configure your network, it
handles all the little ‘bits’ that can be misremembered.

In any case, yes, you create the file, and put the single line:

default 192.168.51.2

within it. first word ‘default’, a space, and then the IP address of your
gateway.
