I added a small watchdog scripts useful for monitoring dial-up devices.
We need this because of unstable UMTS connections far outside of
our office.
If you set "watchdog on" in your interfaces the script checks each
minute if the interface is still present and UP.
After 3 failures the router will be rebooted immediately.
BTW: this is generic and might be used on every kind of interface.
