Are you setting up a VLAN on the modem site of the firewall?  There 
shouldn't be any need for one there.  You normally use a VLAN on the 
local network to keep different types of service separate.  For example, 
I have set up networks where VoIP is on a separate VLAN than the regular 
network traffice or where public WiFi access does cannot connect to the 
local LAN.  Also, VLANs are typically on different subnets.
