„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.
