WLAN2 as Hotspot and WLAN1 as LAN / Separated

Hello Guys,

I’m starting with mikrotik. I’m using a RB2011+WIFI.

I have setup as following:

WAN - ETH0 - Connecting via cable to ADSL Modem in Bridge Mode.
WLAN1 - LAN
WLAN2 - HOTSPOT LAN

I want to block all connections from HOTSPOT LAN to my LAN and allow LAN connections to HOTSPOT without restriction. Is this possible?
