3750 vlan-watchguard firewall

Need some help. I have a watchguard firewall configured as drop-in mode. From the firewall created 2 secondary network 10.100.0.0/21 and 10.100.8.0/21. On the fiewall on a separate interface I assigned the 10.100.8.1/21 On the 3750 have configured vlan1 10.100.0.1 and vlan 5 10.100.8.1. On VLAN1 I have Windows 2008 r2a dhcp server 10.100.0.16 configured with scopes 10.100.0.0 and 10.100.8.0 On the switch I assigned an IP helper address to 10.100.0.16. When I enable the port on the firewall and spoofing and no communication from the DHCP server on 10.100.8.1. Anyone with a watchguard firewall in drop-in mode have any issues configuring VLANS.

Tell me if I am wrong. . From the controller>>>>>Port1 connected to Wood 3750 switch port fa2/0/15(switchport access mode)>>>Wood 3750 is connected on port g/1/0/3 to port G1/0/1 on Massey(Trunk)>>>>Massey port G2/0/3 is connected to Vestal G1/0/3(Trunk). On Vestal fa1/0/1 (switchport mode access)is connected to the firewall Trusted Interface1 (10.100.0.1/21). The firewall external is connected to the ISP router. Vestal fa1/0/16 (switchport access mode)is connected to the firewall Intface3 Optional(10.100.8.1/21).From a laptop I recieve an IP address from the dhcp server. When attempting to browse Internet, it timesout and I get spoofing.
