Failover of gateways
 

Hi all!

I'm trying to configure Debian GNU/Linux with two alternative gateways.
That is to say, that initially the traffic is by GW1 and if it is down
then it goes by GW2. If GW2 is again up, then it becomes to use GW1.

Somebody was able to implement some configuration of this type and could
help me with it or indicate some reference to me?

Thanks in advance for your replies.

Regards,
Daniel

heartbeat, carp etc etc. It's easy under OpenBSD, I've never done it
with Debian but can't be too different. Basically you want an address
that everything points to which actually is a virtual ip address that is
used by whatever is master.

Mmm... but, according to I know, Heartbeat is for implementing HA
between two physical servers. To which I talked about with GW1 and GW2
is to two Internet providers.

Thanks for your replies.

There are some docs available out there:

excuse me, in that case i completely misunderstood you.

but it might still apply ;)

so if i understand correct you have 1 machine and GW1 and GW2 are both
reachable via the same network interface?

or are both gateways on a separate network interface?

Don't worry. It seems that Michal understood the same :-)

In the same machine there are two network interfaces where each of them
corresponds to different gateway.

Thanks for your reply.

This is the script I used to use at home with my two providers:

http://www.carrol.biz/olafrv/06-02-2006-ShellScriptparaCambiarde.html

Maybe you can do some modification and use it.

PD: Sorry about top post I'm on a mobile system can't change it.

Hi all!

I'm trying to configure Debian GNU/Linux with two alternative gateways.
That is to say, that initially the traffic is by GW1 and if it is down
then it goes by GW2. If GW2 is again up, then it becomes to use GW1.

Somebody was able to implement some configuration of this type and could
help me with it or indicate some reference to me?

Thanks in advance for your replies.

Daniel

have a look here

linux advanced routing + TC, there is a how to do multi default
gateways.

I previously used this to do a adls2+ and a cable setup, although you
have to devise a test for each gateway. just pinging the gw isn't good
enough, do you do just past the gw ??

Remembering that you had spoken of heartbeat in this thread, for other
reasons I was testing it but I found that the change of active node
only happens when another node dies and not when the service in another
node stops responding. It is possible to change of active node when the
service in a node does not respond?

Thanks in advance for your reply.

Daniel
