Hi, Michael, and welcome to the User BB!
By default, the firewall blocks all traffic. For example, when you activate Web Filtering in a Transparent mode, WebAdmin creates an (invisible) firewall rule allowing outbound port-80 traffic for the Hosts/Networks in 'Allowed networks' on the 'Global' tab. If you did the default installation, the wizard had WebAdmin create a rule 'Allow : Internal (Network) -> Web Surfing -> Any'.
Inbound traffic also is blocked by default. The ASG/UTM is a stateful firewall - instead of making firewall rules to let requested traffic in, it uses a connection tracker and automatically allows responses to requests it has sent. In general, you won't need firewall rules to let desired traffic in unless you have a server you want to open to the public.
Cheers - Bob
PS Although this question isn't affected, it's always a good idea to include the exact version you're using - 9.004-34?
