I'm connected to the internet and everything is working fine but ZA blocks soooo many attempts (already over 5000 in less than a month) from other computers on the same router as well as from the dhcp ip. Is it possible that my family members' computers have been infected?

Thank you for your help. These are the details for some of the consecutive incoming blocks ZA made.

They all blocked access to port 42017 on my computer (192.168.1.102:8612 and 8611) coming from source ip 192.168.1.103. The source port varies each time (examples,
56814, 15604, 13543, etc. ) These are all UDP protocols.

This is the message I get

"ZoneAlarm blocked traffic to port 42017 on your machine from port 15604 on a remote computer whose IP address is 192.168.1.103. This communication attempt may have been a port scan, or simply one of the millions of unsolicited commercial or network control messages that are routinely sent out over the Internet. Such unsolicited messages are often called Internet background noise."



It has also blocked outgoing TCP SYN protocols from my computer to 192.168.1.101 (ports 42956 to 35584 ), as well as UDP to my DNS ip address (programs like Google chrome[46277 to 47873] and svchost.exe[13568 to 16599])

Another thing that bothers me is that my public ip is set to 192.168.1.0
when my router ip is 192.168.1.1. Should I not be concerned with this?
