ipfwadm syntax

[Terry Williams]

ok I'm using ipfwadm and I would like to open ports 2000-2001 so that I can get streaming video on my windows machines the windows box is ip 192.168.100.2-5 I've checked the docs but it confuses me more then I was before reading them 8) I think the command should be: ipfwadm -F -a accept -b -P tcp -S 0/0 2000:2001 -D 192.168.100.0/2000:2001 And that don't seem to work....   any help would be appreciated.
