Figure 12: Configuration  SecureNow  „Analysis stopped"

Window after exiting the network analysis with a proposed indication of firewall filtering rules. If you click the

button "apply rules", the firewall will be updated with the proposed rules and immediately activated. The

changes are not saved automatically, so that e.g. "wrong" filter rules can be removed by a Router restart.

Then previous filter rules would be valid again.

Figure 13: Configuration  Packet filter  Tab „Layer 3"

This is the window for the manual configuration of firewall filter rules based on Layer 3 (IP layer). The

screenshot shows the firewall settings as delivered with the default rule "Allow_L3*". This rule says that any

IP protocol (*) and any traffic regardless the direction (source and destination=*) is allowed. The result is that

- on delivery - the firewall is "open" on layer 3.

Fore more detailed information about using the packet filter please refer to Appendix A3.
