>Description:

When network is added to the table ipfw in shortened form, network ::/0
appears.

By the context of the rules ipfw - drop or reset, network ::/0 can block
access to the target machine. 

In the system 9.0 such behavior was not observed. 
For example, the network 177.204/14

#whois -L 177.204/14
..
inetnum:     177.204/14
aut-num:     AS18881
abuse-c:     GOI
owner:       Global Village Telecom
..
>How-To-Repeat:
#ipfw table 100 list
#ipfw table 100 add 177.204/14
#ipfw table 100 list
::/0 0
