8.1  Portfilter 

The port filter is the main item of the firewall. Rules are defined in this section, which control 

the whole data traffic. The rules are editable in the properties networks, user, services, and 

time. You can define if traffic which matched with a created rule will be logged. 

By default, traffic will be stopped if no rule is set which allows the traffic. 

 

 

fig. 65  overview of all created rules

 

 

Note: 

You can also define IP-Table rules in the category 

Advanced Settings

 (see chapter 

12.6.5). On the tab 

Templates

 use the 

Application

 

securepoint_firewall
