I just build a new beta box and imported config from 7.402 machine, however, ssh outbound is being dropped although I have rule that allows it. (this rule is imported from old machine).
There are several, unrelated beta bugs that seem to have been resolved, like this one, with a reboot. I suspect that this is not new behavior, and that there is some portion of a restored config that requires a reboot to be reloaded. Elsewhere, I've suggested an automatic reboot-but-ignore-the-USB-memory-stick after a restore, but maybe Astaro can figure out what section of the configuration needs different treatment than the current restore offers.
