access from Trusted to Optional?
I understand how access from DMZ (optional) to trusted is blocked, but what about the other way around? It would seem like by default trusted should be able to have any access to DMZ - is that true? Or do I have to add a new access rule for every type of access.
E.g. if I put a web server on DMZ, and want to test and access it from trusted, do I need to add new rules for every type of access?
(http, https, ssh, ping, ...)
