Could anyone please share a simple 3G failover script? The 3G connection should only be activated when for example 8.8.8.8 is not reachable via ethernets default route and disabled if 8.8.8.8 is reachable via ethernet again.
just have 2 default routes and have a check Gateway arp (or ping) to main gw. low weight to main route, higer to the 3g route. now it should switch automaticly
