Question : Problem: Setting up a VLAN with iner VLAN routing

I am looking at setting up 2 VLAN's on our office network that can inter-communicate with each other over UDP/IP and also communicate with the main office LAN.

Currently we only have a netgear FS526T smart switch with basic VLAN capability, and a Sonicwall pro 2040 as the gateway.

Firstly, can the current hardware be configured to do this? IS I setup the VLANs on the Netgear FS526T and tag each port, can the Sonicwall Pro 2040 be configured to do the routing between the VLAN's? Or will I need a L£ switch?

L3 switch can do the job also, however it is not so sophisticated in filtering as firewall.
So firewall can handle the job also.
