I have a cable line and a dsl line at an install. We need failover and have been using the gateway watch up script and down script.
The problem is this:
If i set the up script to check a location on the internet, and that interface fails, it will execute the down script. However once executed and on the new script the location will be cheked again and register as UP so the interface rolls back over to the non functing interface until it then execfutes the down script.
its an endless loop that does not stop until the main line is back up (defeating the purpose of this tool, for the most part).
What can i do? I know i can ping a gateway one hop away from my modem, but i've seen the circuit go out and my dsl is down, yet the gatway is still pingable from the cable modem.
any ideas?? i really need this working
thanks
