Failover default route?

[Tuc at T-B-O-H.NET]

Hi,

	I know its been talked about before, did 1/2 an
hour of Google... 

	In my case, as always, its a bit "special". I have
2 OPENVPN tunnels, which I sent over different transits to
the same end host. On that host, I do my NAT. SO, without
getting into all sorts of hot/heavy things, is there a simple
program to install to ping something via the first tunnel,
and if it can't then switch my default route to the second
tunnel? Or, do I just use a script like here :
