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 --- "Loren M.
