Multiple VLANs sharing one Internet Connection

I have a Dell PowerConnect 6248 and would like to set up 3 different VLANs that can talk to eachother as well as share a SonicWall Pro 1260 Firewall.

I want set up the 3 different VLANS like this

VLAN1 192.168.1.0/24 - has department 1 computers using 10 ports
VLAN2 192.168.2.0/24 - has department 2 computers using 15 ports
VLAN3 192.168.3.0/24 - has department 3 computers using 5 ports

VLAN1 interface is 192.168.1.1
VLAN2 interface is 192.168.2.1
VLAN3 interface is 192.168.3.1

I would like VLAN 1 and VLAN2 to communicate with each other while neither communicating with  VLAN3

All 3 VLANS should be able to get to the internet using the Sonicwall. Is this possible?

I think im close. I set up the vlans and they do communicate with eachother. I have not set up acls to prevent vlan3 communication yet. The only problem know is that the internet doesnt seem to work. The sonic wall is doing nat translation. is there something i need to configure there?
you need to setup the switch with a default gateway so that it sends all traffic to the sonicwall for routing out to the net
enter
ip route 0.0.0.0 0.0.0.0 x.x.x.x - where x.x.x.x is the sonicwall ip
all client PC's should use the switch IP as there defualt gateway - the switch will then forward the traffic on out to the net - the sonicwalll should be setup to do hide nat (all internal behind one external) then if u set it up right it should work
if not can you do an ipconfig from a client and provide some addresses from the sonicwall and switch ?
