    Hi Loren

    Thank you for your mail again

    For the monitor sofeware iptraf , I can't get it in
    the port. Why freebsd doesn't support it!
    I tried to install in freebsd from the tarball and got
    an error messages!

    I need sth to prove the traffic to those routers from
    outside.

    Do you have experience the max traffic freebsd can
    support? It seems to support max 230M only!

    Thank you
