Hi Rene,
When you say the direction does not matter,does that mean that writing the command like (inside,outside) or (outside,inside) becomes irrelevant.If i compare what you explain when the outside client wants to connect to DMZ server inside,your nat statement is
ASA1(config-network-object)# nat (DMZ,OUTSIDE) static 192.168.2.200
whereas on this link under the second example
https://www.cisco.com/c/en/us/td/docs/security/asa/asa95/configuration/firewall/asa-95-firewall-config/nat-reference.html
NAT for Inside Hosts (Dynamic NAT) and NAT for an Outside Web Server (Static NAT)
Step 5
Configure static NAT for the web server.
hostname(config-network-object)# nat (outside,inside) static 10.1.2.20
its the other way round???Please explain.
