I have 4 VLANS and a Management Interface (LAN)
LAN works peachy with outbound NAT
The 4 VLANS do not
I had automatic rules creation enabled and then I tried hybrid and created a rule
QuoteInterface: WAN
Source: 172.16.0.0/23
Source Port: *
Destination: *
Destination Port: *
Nat Address: WAN Address
Nat Port: *
Static Port: NO
Description: test
All VLAN subnets are indeed listed in the Automatic rules
I can get DHCP address from each VLAN, but I can't get on the net from any subnet.
I suspect what you are missing are firewall rules that allow traffic from the VLAN interfaces, LAN has "default allow" rules which you must replicate in some form on the VLAN interfaces
