Arrow Portscan problem

Hello everyone,

since I've had a big problem with attacs from different schools in China, I looked up all the address space that APNIC is handling and made a network group with all these networks in it. I have also made a packet filter rule on the second place of the list which drops all the traffic with logging from these addresses.

Now I still get portscan messages and the source is an address in one of those ip ranges. To be more specific. I get portscan messages from 61.139.105.163 and I double checked my entry which is 60.0.0.0/7 and that should include the ip address above.

Does anyone have ideas? Is the portscan check made before the packet filter??
