re: new install: network unreachable

["Chris Brown" <CBROWN@seitz.com>]

Hi csani,
You're a genius!....  the ipfwadm -Mf command was rejected, but the
others worked and now I'm back on the net! Can you please explain a
little what was going on and why my config defaulted to
allow_no_network_traffic_mode?

What's the best way to permanently set the correct options?

Many thanks,
Chris.
