        my netgear and pfSense setup surprised me this afternoon.  the
        initial setup listed my internal IP as,

        but something I did changed the DHCP leases section to .

        after that, I could ssh out and then ssh back to tao.

        I havent used ipfw for many years.  the most recent firewall I 
        ran was on FBSD 5.X and was {i think} "pfw".  I got quite good
        at it.  I should learn more about plain "pf" and pfSense.
        do you know if pf/pfsense defaults to DENY incoming connections?
        that would explain a Lot!

        the URL you had was fedora-13; what I installed fedora-17.
        and just recently--maybe when I rebooted--i saw fedora-19[?]
        not sure... .

        well, the deal is that my volunteer system admin worked for 
        red hat for about 5 years.  I'm more used to ubuntu, but my
        friend says that im on my own....

        anyway, things are starting to eork.  [!]
