permanently add static route


There is another network in my office, on a different sub-net, to which I need to connect on a regular basis.

The two sub-nets are connected by a computer with 2 network cards, running a linux software router.

This is what I've been doing to get connected:

Code:
/sbin/route add -net 192.168.1.0 netmask 255.255.255.0 gw 192.168.168.72
Which works fine. The only problem is that this route disappears if I reboot my system. So, what would be the best way to permanently add that route to my system?

Take a look at this script:

/etc/sysconfig/network-scripts/ifup-routes

It references a file called /etc/static-routes. It looks like you list them there and this file will handle adding them to the routing table for you on bootup.

I don't have a file called 'static-routes' anywhere on my system.

my gateways etc.. are defined in /etc/sysconfig/network.

Acid, do static routes go there? if so, what's the syntax?

The /etc/sysconfig/network-scripts/ifup-routes specifically looks for /etc/sysconfig/static-routes, if the file isn't found it simply exits, but if not, it parses the entries one line at a time doing a "/sbin/route add -$args" on each entry.

All you should need to do is create that file and put in the following line:

eth0 net 192.168.1.0 netmask 255.255.255.0 gw 192.168.168.72

of course if your nic isn't eth0, use whatever is appropriate for your system.

mine just says

NETWORKING=yes
FORWARD_IPV4=false
HOSTNAME=trevor
GATEWAY=10.0.0.2

and i *think* that's all the parameters there are. i think you can alternatively speciffy the interface to use rather than the IP with GATEDEV= or something, but that's it.

Yeah, that is how you setup your default gw, but in order to setup a static route you need more information than that. I honestly don't think you can put a static route definition in there. I suspect the script that sources that file is only looking for the information you listed.

hi

your problems are solved if you add that route add statement in /etc/rc.d/rc.local file , every time your machine starts this will be executed and your route tables are updated,

Until you ever upgrade your initscripts package, then rc.local will get overwritten

The correct way to add a permanent is as follows...

I know this is an old thread but it kills me to see people using the rc.local file for this. This is not the right way to do this.
The correct way to add permanent static routes to a system besides setting the default gateway is to create a file /etc/sysconfig/network-scripts/route-eth0 (or whichever interface you want to route through). You can add as many routes as you would like per interface by simply incrementing the number at the end of each statement. Once saved a restart of the network services will force a read of this route file.
The syntax of the file should look like this:
ADDRESS0=x.x.x.x
GATEWAY0=x.x.x.x
NETMASK0=x.x.x.x
ADDRESS1=x.x.x.x
GATEWAY1=x.x.x.x
NETMASK1=x.x.x.x

Enjoy!

Thank you jrwsod,

Was finding a lot of different ways, this looks like the right and most simple way. Worked perfectly (ofcourse..)

Hi,
I cannot understand your conception (what do you wont to achieve), bu change parent of filters to 1: (filter ... parent 1. Now the packets will be directed to 1:2 class.

is "/etc/sysconfig/static_routes" deprecated in rhel?

Sometime people say using "/etc/sysconfig/network-scripts/route-ethx"; sometime people say using "/etc/sysconfig/static_routes", this only makes me confusing.
