t23# ipfw -q add 137 deny all from 180.0.0.0/8 to any
t23# ipfw show 137
00137    0       0 deny ip from 180.0.0.0/8 to any

So what doesn't work?  (apart from scattergun removal of small pieces of
a whole lot of Asian countries, incl. Japan, Indonesia, Australia, .. :)
it was intended as a required temporary measure,
but even though it was listed in my ipfw list, i was/am still seeing traffic coming in via addresses such as 180.248.x.x


A very open firewall test script is as follows:

00010 allow ip from any to any via lo0
00081 deny log ip from 180.0.0.0/8 to any
00100 check-state
00101 allow tcp from any to any established
00102 allow ip from any to any out keep-state
00103 allow icmp from any to any
65535 deny ip from any to any

but i'm still seeing traffic from

180.149.29.102
180.234.116.61
180.234.36.44
180.234.237.119
180.234.72.115

I must be doing something wrong!
Paul.





cheers, Ian
