Why you have hardware firewalls
I have a hardware firewall on my line here and the firewall log for the last 24 hours shows just why it is needed.
Starting at about 8PM local time a Chinese IP address 61.172.249.201, belonging to Beijing Waei Software Development, has been sending spam packets to my IP address at approximately 2 minute intervals. From 8PM last night to 9AM this morning I received just under 400 packets with another 300 to 5PM tonight all directed at ports 1026 and 1027.
I don't know if this is a case of a spammer gone crazy or a form of a denial of service attack. Either way, the firewall is dropping the packets in the bit bucket so I am clear.
I sure am glad I shelled out the cash for the firewall.
Meanwhile, to help reduce network traffic I have sent a report to snipped-for-privacy@ccert.edu.cn and snipped-for-privacy@ccert.edu.cn to see if they can stop the attacks.
Does anyone have any further suggestions?
