I am trying to set up a spare default route in case the primary route is down. The router in question is a Linux machine having access to three upstream connections and to the DMZ. I do not want to have routing daemons on the box, I simply want to change the default route in case the primary connection (which supplies the LAN behind the DMZ) is down. The only thing I have come up so far (I do not want to have fancy things like zebra, routed or gated on this machine) is a Perl script that measures the connectivity and takes action if it detects that the route is down. Does anyone have a better idea? (I am willing to to a nice and tidy ASCIIgram if you like ;-) Cheers, René GNU/Linux Manages! - Linux Solution Provider RP551296-NICAT - Open Software for Open Minds
