I want to use my eth0 interface as my primary wan and the 3g (wan2)
connection as a backup, and 3G should only be used when the primary
wan (eth0) isn't working.
I've been reading through http://wiki.openwrt.org/doc/recipes/3gdongle
but a few points aren't clear to me.
1) how can i achieve that the wan2 (==ppp) is used as a backup
interface (in the example it looks to be balanced ( i do see equal
weight statements))
2) what's the meaning of setting option 'defaultroute' '0'  (in the
document is stated that both peerdns and defaultroute should be set to
0, but i only do see defaultroute)
3) where can i find more information on the option possibilities for
config interface and config multiwan


thx in advance for your reply
