13.7 Firewall Technical Reference
This section provides some technical background information about the topics covered in this chapter.
13.7.1 Firewall Rules Overview
Your customized rules take precedence and override the Zyxel Device’s default settings. The Zyxel
Device checks the source IP address, destination IP address and IP protocol type of network traffic
against the firewall rules (in the order you list them). When the traffic matches a rule, the Zyxel Device
takes the action specified in the rule.
Firewall rules are grouped based on the direction of travel of packets to which they apply:
By default, the Zyxel Device’s stateful packet inspection allows packets traveling in the following
directions:
• LAN to Router
These rules specify which computers on the LAN can manage the Zyxel Device (remote
management).
Note: You can also configure the remote management settings to allow only a specific
computer to manage the Zyxel Device.
• LAN to WAN
These rules specify which computers on the LAN can access which computers or services on the
WAN.
By default, the Zyxel Device’s stateful packet inspection drops packets traveling in the following
directions:
•WAN to LAN
These rules specify which computers on the WAN can access which computers or services on the
LAN.
Note: You also need to configure NAT port forwarding (or full featured NAT address mapping
rules) to allow computers on the WAN to access devices on the LAN.
