Zyxel NXC2500 / NWA3560 guest WIFI

Hi

Is anyone aware of an easy to follow guide that describes setting up a Guest WiFi using the Zyxel NXC2500 / NWA3560 Combination?

I have these, along with 2 ADSL modem routers each configured and ready to plug into sockets 1 and 2 on the NXC. I have managed to get Corporate Wifi set up and working via port 1 ADSL, whilst having the NWAs plugged into ports 3 4 5 and 6, but I'm unable to get guest wifi out via port 2 when I set up VLANs.

Cheers
