ipfwadm -I -i reject -S 192.168.2.1/24 -P tcp -D 0/0 80

In this example, every coming from 192.168.2.* and going to port 80/tcp is
blocked in input (-I). If you wish to block also forwarding (for example,
to internet), the same line but -I -> -F.

Please, try also the script "ipf" in muLinux: it is a sort of "fdisk"
for IP filtering.
