I've tried several variations of this with limited success:

  Script started on Thu Mar 13 12:26:27 2003
   
   # ifconfig xl0 inet 209.122.66.XXX netmask 255.255.255.0

   # 
   add net 10.0.0.0: gateway xl0
   
   # route add -net default -iface -interface xl0
   # 
   add net default: gateway xl0

   ping: sendto: Host is down
   ping: sendto: Host is down
   ping: sendto: Host is down
   ping: sendto: Host is down

So this method allows my system to get to the 
modem/dhcp server/gateway, but no further. (when I ping
from windows I get a response, so the system isn't down.)

I get the same result with only the ifconfig and route add -net default
and doing route add -net 10.17.47.37/32 -iface xl0 rather than 10.0.0.0
gives the same results.

Any further thoughts or ideas on how to resolve this???

Thankd

Jim
