Setting the time

The time you specify for From must be earlier than the time you specify for To , e.g. if you

enter "08:00" in From and "17:31" in To, the rule will apply from 8:00am until 5:31pm.

Time periods begin and end at midnight. Therefore, to apply the rule to a time period

between a given time and midnight, enter the time in From, and leave To blank, e.g. if you

enter "17:31" in From, the rule will apply from 5:31pm until midnight. To apply the rule to

a time between midnight and a given time, enter the time in To, and leave From blank, e.g.

if you enter "08:00" in To, the rule will apply from midnight until 8:00am. To apply the rule

overnight, e.g. from 17:31 to 08:00, you need two rules.

Configuring firewall events and alarms

The last item in the Firewall submenu is Events. The Events menu item enables you to set

some parameters that are general to the Firewall module as a whole. These are not

policy-specific parameters.

Clicking Events displays the Configure Firewall Events screen, as shown in Figure 12. This

screen shows two tabs, logging options and alarms.

Logging options tab

The Logging options tab allows you to determine which types of events will be recorded

into the router log. You can log the start time and beginning of flow of allowed inbound

and/or outbound flows. You can also log deny events on inbound and/or outbound

packets.

Figure 16: An example of the firewall events logging options window

For each type of event that you decide to log, you have the option of a simple log entry, or

a more comprehensive, 'extended' log entry.
