This completes setup of NAT-incompatible services on the server in your DMZ. Now users
can access the file server on your DMZ from the Internet.
4.3 Firewall Rule Setup
Your ZyXEL Device’s firewall default settings provide network security by allowing traffic
from the WAN to your DMZ, and blocking traffic from the DMZ to the LAN. However, you
can further enhance network security by defining firewall rules specifically for traffic from the
WAN to the DMZ.
