Permamanently Add a route to the kernels IP routing table

Alexander Fedyashov — Wed, 08 Aug 2007 17:32:11 GMT

I (a newbie) can add a default route to the kernels IP routing table by issuing:
route add default eth0

The change only lasts up until the next boot. How can I permanently add the route to kernels IP routing table?

ANy help would be appreciated.

There are a number of ways to do it, and some of them depend on the distribution you are using.

As you are wanting to change the default route, there's always a nice way to do it.

On a RedHat system, you modify the 'GATEWAY=' line in '/etc/sysconfig/network' for instance.

On all distributions, you'll have some sort of network manager which will give you a GUI to do it as well.

If all else fails, you can add your 'route add' line to '/etc/rc.d/rc.local'. This is the least maintainable method however, as no system utilities know of it.

Hi Stuart,
I'm trying to add a default route. The Route command lists no default route. I'm using REd Hat Linux.

Thanks,
Alex
