The following screenshot shows the Firestarter user interface:

The events of concern to us are ones in red. These indicate that the firewall rejected attempts by the systems at IP address 192.168.2.16 and 192.168.2.18 to establish SSH connections with our system. SSH is a protocol for establishing remote connections between computer systems for the purposes of creating a terminal session, executing programs and transferring files. Clearly such an event is a matter of concern, but fortunately the firewall detected and blocked the connection for us.
Right clicking on a blocked event in the list displays a menu containing a number of options. From this menu it is possible to allow connections from this external IP address (for example if you find the access attempt was valid), enable connections of this type from any source and also disable the port used for this type of connection. It is also possible to look up host names so that system names, rather than IP addresses are displayed.
