Configurating multi-WAN in varius VLAN

[lfdominguez]

I have this situation, a pfSense server that have 3 NICs, one of them is connected to a Layer 2 Switch and the others routers connected to this. Figure:

Router 1 –--------------------------------------
                                                      |
Router 2 (Internet) ------------- [ Layer 2 Switch ] –-----------  pfSense
                                                      |
Router 3 ----------------------------------------

Router 1 has 190.140.0.16
Router 2 has 192.168.0.15
Router 3 has 10.12.14.10

in the pfSense i configure the wan interface with the ip 192.168.0.16 and GW 192.168.0.15 (Router 2) and with two VLANs with the WAN interface as parent with IP 190.140.0.17 and GW  190.140.0.16 and the other .....

The problem is that the pfSense has ping with the Router 2, but with the VLANs not, is timed out or "ping: sendto: Host is down"

In the routers i need to configurate to support VLAN?? or something else??? the switch need support VLAN???
