Port 138 SMB & Dynamic Ports 49181 & 49182

Post by LLCoolJ94 » Thu Jun 21, 2018 7:54 pm

While running the Log Visualizer I noticed that my firewall blocked several incoming connection attempts from:

IP: 192.168.1.202
Port 138
SMB

I know that macOS uses this port for NETBIOS, however, I am wondering if receiving several attempts (4 or 5) for an inbound connection within about 30 minutes is normal? I have no reason to share a drive with the internet, so I am not sure what is trying to communicate with my machine.

I also noticed I'm blocking an inbound connection from:

IP: 96.17.164.88
Port 49181
Dynamic Ports

IP: 17.248.185.72
Port 49182
Dynamic Ports

Using the query function I found that these traces back to Apple.

Any thoughts?
