Interface Statistics



  • Folks Im loosing my mind here trying to understand why and how the bytes-out is several times more than bytes-in on my interfaces. Does Bytes-Out mean traffic sourced externally or traffic destined externally in relation to the interface network?

    bytes out of an interface is just that - bytes out of an interface..

    So what interface are you looking at?

    Wan or Lan?  If your using… Normally your out on your wan would be lower then in to your wan.. And out on your lan would be higher than your in..

    Since users normally download more than they upload...

    internet ----> wan (pfsense) lan -----> user

    So you see that its in to wan and out of lan..

    If your talking 2 lan interfaces than the in out tell you in what direction most of the traffic is flowing.



  • That's what I'm seeing but why is OUT on LAN higher than IN if users are downloading data (or bringing data IN to their device). Seems reversed.



  • Even stranger is when I view the traffic graph, the graph display shows opt1 out as 20M but the text shows my host BW-In as 20M. Its like the graph is reversed from the text reading.

    Because as they Download the file from the internet… The Data flows from the internet -- see my little asci diagram with the ----->

    Is IN to the wan, and OUT the lan to the user..

    The users interface will show IN as high and out as lower.. Look at the users interface on their machine..  Is the packet coming into the interface from the wire out to the wire is how you have to look at it.

    NOW I GET IT!!!! I wasn't considering the internal router interface going OUT and then IN to the users local interface. Thanks for clearing me up. :)
