mdemel,
i have the same exact situation, and i’ve had it ever since ZS 1 beta 15 or so: i’ve had it with a satellite modem, and three different kinds of DSL modems. I’ve had it with new and old profiles: link goes down and comes back up, however NetBalancer doesn’t realizes it’s back up until i manually de-activate it and re-activate it, which defeats the entire purpose of having the FailOver feature in the first place. I’m still using NetBalancer for IP address based routing.
Did you figure something out?
