--- Comment #3 from smithi at nimnet.asn.au ---
Confirming that this issue existed on 8.2 and <cough> 5.5-stable.
On 8.2 anyway, while the table entry is not listed, it does work:

t23# ipfw table all list
t23# ipfw table 9 add 255.255.255.255
t23# ipfw table 9 add 255.255.255.255
ipfw: setsockopt(IP_FW_TABLE_ADD): File exists
t23# ipfw table 9 list
t23# ipfw add 1000 count log ip4 from any to table\(9\)
01000 count log ip4 from any to table(9)
t23# ping 255.255.255.255
PING 255.255.255.255 (255.255.255.255): 56 data bytes
