Unable to reach hosts outside my subnet after initial install

After a fresh installation of freeBSD 7.0, I am unable to communicate
with any hosts beyond the local subnet.  All important values
(gateway, netmask,etc) were copied from other unix hosts on the same
subnet.  Presumably I've either failed to include something important
or there is a conflict. Details follow...

thanks for any assistance,

here's the current net config:

Here's the contents of /etc/rc.conf:

  Finally, the current situation is that I can ping hosts on the 128.32.157.*
subnet, but not anything beyond.
