The ordering of your rules is very important as rules are applied in the order
that they are listed.
See

The firewall rules are grouped by the direction of packet travel. This displays the
number of rules for each packet direction. Click the edit icon to go to a summary
screen of the rules for that packet direction.
Here is an example description of the directions of travel.
From LAN To LAN means packets traveling from a computer on one LAN subnet to
a computer on another LAN subnet on the LAN interface of the ZyXEL Device or the
ZyXEL Device itself. The ZyXEL Device does not apply the firewall to packets
traveling from a LAN computer to another LAN computer on the same subnet.
Use the drop-down list box to set the firewall’s default actions based on the direction
of travel of packets.
Select Drop to silently discard the packets without sending a TCP reset packet or an
ICMP destination-unreachable message to the sender.
Select Reject to deny the packets and send a TCP reset packet (for a TCP packet)
or an ICMP destination-unreachable message (for a UDP packet) to the sender.
Select Permit to allow the passage of the packets.
Log
Select the check box next to a direction of packet travel to create a log when the
above action is taken for packets that are traveling in that direction and do not match
any of your customized rules.

Click Apply to save your changes.
