Cisco 3550 Multicast Settings

I have some handheld devices that get messages from a multicast message.   The issue I am having is this.  

Orginally in a test setup the devices were setup on the same IP subnet (192.168.2.0/24 and VLAN 10) as the server sending the messages.   Now in deployment the devices are on a seprate subnet (192.168.3.0/24 and VLAN 13) and none of the packets seem to be making thier way to the devices.  

How do I enable the routing in the 3550 or my firewall device/router so that the packets get to the new subnet?

The messages are being send to an IP of 239.192.2.2

Below is the Cisco 3550 switch config (the parts that I think matter)

interface Vlan1
 no ip address
 shutdown
!
interface Vlan10
 ip address 192.168.2.102 255.255.255.0
!
interface Vlan11
 no ip address
!
interface Vlan13
 ip address 192.168.3.1 255.255.255.0
 ip helper-address 192.168.2.16
!
interface Vlan110
 ip address 10.192.21.90 255.255.255.192
 ip helper-address 192.168.2.16
!
ip default-gateway 192.168.2.2
ip classless
ip route 0.0.0.0 0.0.0.0 192.168.2.2
ip route 137.192.230.7 255.255.255.255 10.192.21.94
ip route 199.86.96.177 255.255.255.255 10.192.21.94
