ok...i understand. you need to add a route then. go to the sonicwall and go to Network > Routing. Click Add Route on the right. Source: Any; Destination: 10.2.1.0/24; Service: Any; Gateway: 10.1.1.x (whatever this IP address is for the Cisco); Interface: LAN or X0. Click OK. I have to assume that the Cisco has an IP on the LAN side of 10.1.1.x. Whenever there is a request to get to 10.2.1.x, the sonicwall will send it to the Cisco. You need to make the sonicwall aware of the 10.2.1.x and how to get traffic to/from there/
