Can I configure Astaro v6.102 to refuse to route to a particular subnet?
What I want is that for computers on the internal network that have the Astaro gateway set as their default route should still not have a valid route for a particular subnet. Any attempt to route to that subnet should fail unless it is explicitly defined, so it has to fail if sent to the default route.
I already tried rejecting packets with that subnet destination in the packet filter, and it did not help. A traceroute from the internal network to an address on that subnet still shows it routing to the external network.
