>Description:
Hello,
I have a problem with ipfw. After flush there are still entries in table!

root@[******] /var/log/ipfw# ipfw table 123 flush
root@[******] /var/log/ipfw# ipfw table 123 list
*.72.124.140/32 0
root@[******] /var/log/ipfw# uname -a
FreeBSD ****** 8.2-RELEASE-p2 FreeBSD 8.2-RELEASE-p2 #2: Fri Jul 15 03:01:58 CEST 2011
root@[******] /var/log/ipfw#

before flush table 123 has about 100 entries
