Can't Pass Traffic on my SonicWall NSA 240

Hi, I need some help configuring a SonicWall NSA 240 with Enhanced 3.x OS

I have a network that consists of a Sonicwall NSA 240, three Linksys switch’s, some thin clients plugged into the Linksys switches and a server for the Thin Clients. I’m extending my network and placing some thin clients in other locations. I am attempting to do this by using my NSA 240 to segregate my network (exactly like I am currently doing  with 2 other networks using NSA 4500’s). However, I haven’t been very successful. My current NSA 240 setup is this:

WAN = Transparent Mode – 201.50.0.10 – 255.255.0.0
Interface X3 = Thin Clients – Transparent Mode – Assigned a Thin Client Zone
Interface X8 = Server – Transparent Mode – Assigned a To a Server zone
Thin Clients Address Object - range from 201.50.2.130 – 180 - Assigned to the Thin Client Interface
Server Address Object is 201.50.2.1 - Assigned a to the Server Interface
Extended Thin Clients = 100 – 120 IP range coming in from WAN assigned to the Wan Interface

Firewall = Wide Open / Bi-Directional / any-any
Thin Clients setup with Static IP info

** Future setup will involve other networks passing through the WAN – 201.50.X.X and 201.50.X.X **

I’m trying to route my thin client switch’s into Interface X3 and out of Interface X8 and my extended clients coming in on the WAN (X1) to Interface X8 (when I route my WAN traffic out of an interface and into the thin client switch’s the thin client traffic starts going into the SonicWall and dropping packets instead of going straight to the Thin client server).  Although I see that the traffic is getting to the NSA 240 and the ARP cache is building, the SonicWall keeps dropping “ARP” requests and “BOOTP” requests.

Any suggestion would be greatly appreciated.
