Why are packets are dropping everywhere?



  • the setup:
    used Single Lan multi Wan - i have one wan one lan
    3m symmetrical so i used 2.91m in wizard
    otherslow are mail protocols specifically IMAP that takes all the bw
    othershigh http

    questions:
    why almost as much dropped high as low?
    why any dropped on lan?
    if I am correct in this being wrong, how do I fix?

    See attachment and thanks for any help.



  • Increase your queue lengths. They default to 50. I have my high bandwidth queues, like web browsing, in the 5,000 length range, or 2,500 for less bursty traffic, but I have 50mb.

    I also use the "codel" queue management for each queue, except for queues that shouldn't drop packets. It drops packets based on time spent in queue with a target of 5ms or less. I don't know how PFSense has it implemented, but if it's implemented to spec, just set the length to something long enough and use codel.
