I didn't do that, I had a look at the GUI network management stuff, and 
fixed an errant subnet mask, and removed the default route from the rge0 
interface.  I don't think IPv6 is an issue, but it's working now :

  netstat -rn

I haven't tried yet, but will do tonight when it won't disrupt my users 
much.

Thanks!
