Best Guess log ports flipped #488

Closed ee-hex-ee closed 3 weeks ago

ee-hex-ee commented 3 weeks ago

My results in bestguess.log are backward. The instances I have matching are destination port 53 and source port 44818. This is flagging ENIP/Rockwell traffic for some reason where this is actually DNS information in the log itself.
