change ip address of iseries. *DFTROUTE route not available.

I have a sonicwall tz250. I created a DMZ with a different ip address group (192.168.10.1) and plugged my iseries into it. I made the changes on the iseries as follows:

tcp/ip interface
192.168.10.2 255.255.255.0 ETHLINE *ELAN

Tcp/ip routes
*DFTROUTE *NONE 192.168.10.1 *NONE

When i do a netstat, it says route not available:
Route Subnet Next Route
Destination Mask Hop Available
127.0.0.0 255.0.0.0 *DIRECT *YES
192.168.10.0 255.255.255.0 *DIRECT *YES
224.0.0.0 240.0.0.0 *DIRECT *YES
224.0.0.0 240.0.0.0 *DIRECT *YES
*DFTROUTE *NONE 192.168.10.1 *NO

I tried plugging a pc into the sonicwall and it worked fine so it appears the sonicwall is configured correctly.

Any suggestions?
