So here's the network:

Lots of local users, 192.168.12.x.  Users are given an IP thru DHCP, and their default GW is 192.168.12.254.  The 254 addy is a Cisco 3560G switch.  In the configs of the 3560, we have a line that says

ip route 0.0.0.0 0.0.0.0 192.168.12.253

The 253 is our Cisco ASA 5505.

Now I have setup a Sonicwall to replace the ASA, and am just doing some testing.  I assigned an internal IP to the Sonicwall of 192.168.12.252.  If I set up PCs with a def gw of 12.252, everything is fine, they can surf and all that.  If I reconfigure the Cisco 3560G to say

ip route 0.0.0.0 0.0.0.0 192.168.12.252

No one can go anywhere.

What excatly am I missing here??
