 Hey there,
 
 I've confirmed that this is indeed correct.  IPFW2 is limited to 30 
 ports/ranges, and returns 'ipfw: getsockopt(IP_FW_ADD): Invalid 
 argument' when trying to use more than 30, while IPFW1 complains more 
 gracefully with 'ipfw: too many ports (max is 10)' when trying to use 
 more than 10.
 
 Here's a patch for ipfw.8 which hopefully corrects the problem.
 
 Cheers,
 Marc
