Routing question

Background Info:

I have a HP Procurve switch with 8 port based VLans associated with it.

192.168.1.X - Clients
192.168.2.X - Clients
192.168.3.X - Wireless
192.168.4.X - Servers
....
....
....
192.168.8.X - Firewall

Each VLAN on the switch is programmed with a gateway at .1
Example:
VLAN 1 gateway is 192.168.1.1
VLAN 2 gateway is 192.168.2.1
VLAN 8 gateway is 192.168.8.1

The internal interface of the firewall is 192.168.8.2

IP routing is enabled on the switch and there is a default route:
0.0.0.0/0 192.168.8.2


Problem:

Only devices on the 8.X segment can ping the firewall and travel out to the internet.

Question:

What settings in the configuration of the Astaro UTM do I need to change to allow traffic from other internal networks(port based VLANs) out to the internet?

I tried creating a new network definition for the network 192.168.1.0 /24 with the interface set to "any". From here would i then setup a static route? Would I set up a interface route with the "internal interface"? or...Would I set up a gateway route with 192.168.8.1 for the gateway host?

Thanks in advance for any help provided!
