The three things that have changed for me:

- using re0 which I never used before

- using PF. I enabled with:

modload /usr/lkm/pf.o

pfctl -ef /etc/pf.conf

And my config is simply:

tx:reed$ egrep -v '^$|^#' /etc/pf.conf  
nat on ral0 from !(ral0) -> (ral0:0

- And "sysctl -w net.inet.ip.forwarding=1"

(I did those three things to share network for an IP phone.)

I am no longer using re0 -- it is UP by default (as it always was) -- but 
nothing plugged into it. And I don't have pf module loaded and forwarding 
is 0 (default). Hopefully my system will be stable now.
