Portscan Detection On Lan Pcie Card

I am getting continually messages that a portscan is detected and blocking ipaddress which is in use by my lan Realtec PCIe GBE Family Controller. (ipconfig /all : shows the info)


1. Why is my firewall blocking my LAN Card, is that normal btw?


2. What is the solution to end this blocking or these messages?


Thanks in advance.
