If you are a firewall newbie I recommend you skip this section and go to the next which will guide
you step by step through configuration.
Guarddog's user interface is split across three panes. The first pane is "General" and has general
settings controlling how your machine connects to the internet and other miscellaneous options
that control firewall policy.
- Internet Connection - Specifies the network interface by which your system connects to the
net.
- Packet Blocking - Specifies the method to use when blocking packets. It can be either
'DENY' or 'REJECT'. 'DENY' means that a blocked packet is just blocked and now other action is
taken. 'REJECT' means that when a packet is blocked a packet is send back to the source saying
to inform it about the fate of the blocked packet.
- Log Blocked Packets - Should blocked packets be logged to syslog.
- Allow Ping Replies - Should our system reply to incoming pings.
- Log Ping - Should incoming ping requests be logged.
