reboot on problem

[Aleksander Rozman - Andy]

Hi !

I am running FreeBSD as server. Thing is working great, there is only 
one problem. Sometimes machine looses connection to internet... Which is 
quite a problem, since this computer is on remote location, which I only 
access once a week or less. I would need application (or something), 
which would check if computer can connect to gateway, in case that it 
can it would do nothing, but in case it can't it would make soft reboot...

Is there anything that I could achive this with? Any idea is welcome... 
Please cc: message to my private address (reply all should do this)

Thanks in advance
Andy
