When the device uses the firewall rules to generate the filter list, the entries are sorted automatically. The "degree of detail" is considered here: The first rules to be processed are those that have been specified, followed by the general ones (e.g. deny-all).
If the automatic sorting does not produce the desired behavior from the firewall, the priority can be modified manually. The higher the priority of the firewall rule, the higher the corresponding filter is placed in the filter list.
Note: For complex rule sets, check the filter list as described in the section Firewall diagnosis.
