Comodo Blocks Intrusion Attempts by Network Computer (Router)??

Hello, Im new to Comodo!

In Comodo “Network Defense” stands: The firewall has blocked 24 intrusion attempts.
If i look into details, i see that the Intrusions come mostly from:

“windows operating system / blocked / Protocol: UDP / Source IP / source: 138 / Destination Ip: / destination 138/”

I am behind a router and the second computer has the IP
Am I getting hacked by the person behind the second computer??

  • the first question Comodo made was if i want to block IP, the destination was my router ip. should i block it?
