 I can confirm this issue also exists on 8.2 as of today.  It appears as
 if ipfw is incorrectly assuming that an IPv6 address is an invalid IPv4
 address with a mask.
 
 For example:
 2001:1:2:3::4,2001:1:2:3::5 is treated as an IPv4 address of 2001 with a
 mask of 1:2:3::4 (as if it were specified as 1.2.3.4:255.255.255.0).
 
 Specifying the IPv6 address without the comma results in a successful
 rule being created.
