As an example, 1.2.3.4:255.0.255.0 or 1.0.3.0:255.0.255.0 will match 1.*.3.*. This form is advised only for non-contiguous masks. It is better to resort to the addr/masklen for= mat for contiguous masks, which is more compact and less e= r- ror-prone. ........... I tried to set rule to block many broadcasts from several subnets ipfw add deny ip from any to 1.2.0.255:0.0.255.0 but when I look at created rules table with 'ipfw show' I see: .... 03300 0 0 deny ip from any to 0.0.0.0:0.0.255.0 .... This is not I expected and manual page says about it. I expected: 03300 0 0 deny ip from any to 1.2.0.255:0.0.255.0 Perhaps I don't understand something. --=20 You are receiving this mail because: You are the assignee for the bug.=
