9.3 Packet Direction Examples
Firewall rules are grouped based on the direction of travel of packets to which they apply. This
section gives some examples of why you might configure firewall rules for specific
connection directions.
By default, the ZyXEL Device allows packets traveling in the following directions.:
• LAN to LAN
These rules specify which computers on the LAN can manage the
ZyXEL Device (remote management) and communicate between
networks or subnets connected to the LAN interface (IP alias).
"
You can also configure the remote management
settings to allow only a specific computer to
manage the ZyXEL Device.
• LAN to WAN
1
These rules specify which computers on the LAN can access which
computers or services connected to WAN 1. See
