[Question] Block all but local connections within specific subnet, for entire system?

[scottmudge]

I've tried playing around with custom rules to get this to work, but maybe someone can shed some light on how to go about this?

I'd like to control the network on a particular machine to only be reachable (and to only reach) the local subnet 192.168.0.0/16. So the parameters for the rule:

• Apply to ALL Applications
• BLOCK ALL connections by default.
• ALLOW only connections to 192.168.0.0/16

I've tried to create two separate rules, one to BLOCK all connections, and then another to ALLOW connections to 192.168.0.0/16, but the BLOCK rule seemed to override the allow rule.

Is there a way to combine this into a single rule?
