Access This field displays whether the firewall silently discards packets (deny), discards
packets and sends a TCP reset packet to the sender (reject) or permits the
passage of packets (allow).

rule or not.
Add icon Click the Add icon in the heading row to add a new first entry.
The Active icon displays whether the rule is enabled or not. Click it to activate or
deactivate the rule. Make sure you click Apply to save and apply the change.
Click the Edit icon to go to the screen where you can edit the rule on the ZyWALL.
Click the Add icon in an entry to add a rule below the current entry.
Click the Remove icon to delete an existing rule from the ZyWALL. A window
displays asking you to confirm that you want to delete the rule. Note that
subsequent firewall rules move up by one when you take this action.
In a numbered list, click the Move to N icon to display a field to type an index
number for where you want to put that rule and press [ENTER] to move the rule to
the number that you typed. For example, if you type 6, the rule you are moving
becomes number 6 and the previous rule 6 (if there is one) gets pushed up (or
down) one.
The ordering of your rules is important as they are applied in order of their
numbering.
