PfSense + wifi (OpenWRT) guest VLAN

pablot

Hi, let me explain my setup so I can explain my problem…

I have pfSense installed with three NICS, 2 WANS and 1 LAN. On the LAN side I have a Netgear R7000 with Xwrt-Vortex working as an AP for my internal WLAN and I've added a TP-Link WDR-3600 with OpenWRT firmware that I intend to make it serve as a Guest WLAN.

I've already configured VLAN3 on my pfSense box and tried to configure VLAN3 also on OpenWRT but something must be wrong, because I cannot pass the point of my guest WLAN clients trying to get an IP from the DHCP server and just keeping stucked at that point.

I've followed this tutorial to configure my setup: https://mega.nz/#!MV9VSCyK!vcl945m0GxwRTQbN31RpZFwMRJBVSPBiK46nKCV_koY or http://uploaded.net/file/68t63wmx

My LAN/WLAN is 192.168.2.0 and the wifi guest is 192.168.3.0 with SSID pablot_guests

Here are some screenshots from both pfSense and OpenWRT so it can be checked by anyone willing to help me.
WAN and WAN6 on OpenWRT are not used and I think I can safely remove them.

I will reply to myself as I've found the problem so anyone with the same hardware can use this as a solution.

The problem was that the VLAN3 on the WDR3600 was incorrectly set to the interface eth1.3 and on the WDR-3600 the switch is on the eth0 interface, so the VLAN3 had to be set to eth0.3 and voila! everything works!!!

The only thing that should be added to this setup are the firewall rules, that I have set as the following screenshot shows.
