Figure 19 – Firewall Settings
On the main firewall settings page you will find one table for input, output or prerouting rules and a
switch to enable or disable the firewall. Within the tables you can insert new rules, modify existing
ones, delete rules and change their position by moving up or down.
The position of a rule within the list is very important, because the list is worked through from top to
down. If a packet is dropped in the first lines by a very general rule, it does not help to accept it further
down with a more specific rule. So please check the rules right position after defining or modifying
them.
To specify a new firewall rule please click Add New Rule and choose type of rule, it's source,
destination parameters.
