I would like to know if all of your devices will do the following:
Primary Connection: Comcast Cable Modem (STATIC) WAN
Secondary Connection: Virgin Mobile Novatel Ovation MC760 USB 3G
I want to make sure there is no ping and absolutely no traffic going through the 3G until the primary connection actually fails as I do not want any usage of the 3G data plan until absolutely necessary. Most failover solutions always send pings to monitor the interfaces and that would generate data usage on the 3G connection which I am trying to avoid.
I need a very firm answer. Please provide me with a complete answer reiterating in your own words what I am asking.
