connection directions.
By default, the ZyXEL Device allows packets traveling in the following directions.:

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.
These rules specify which computers on the LAN can access which
computers or services connected to WAN 1. See
