How to start dhcp on a separate vlan

[asle_500g]

I have a 500gp that I have been operating in access point mode. (Firmware latest by Oleg -pmon_ver=CFE, 3.91.7.0boot_local=1.9.2.7-8 ) I have now separated one of the lan ports into a separate vlan to be used as an open network that is only allowed access to the internet and not the rest of my internal lan. However I have some problems. My freshly created vlan is vlan2. I will also set up some firewall rules but for now I have disabled the firewall via the web interface. Can anyone help me?
