How To Identify What Port or App is Using Traffic?

[Binson_Buzz]

I have one device on my network which gets occasional traffic spikes. What's the easiest way for me on pfSense to see what port the traffic is coming in on so I can control it?

Thanks

Check out the ntopng package. It could be helpful for what you're trying to do. Youtube has some good informational and instructional videos on the package if you're not sure it'll work for you.

@Binson_Buzz Glad that helped. The people behind the package did an awesome job. It checks many boxes and does them all so well. That's why it's so easy to recommend.
