Trying to get my head round how to setup a RB750.

Its a simple config, i just need to connect multiple clients (probably mostly smart phones) to my Windows 7 server. The clients will be connected via a WLAN, so i need to use DHCP.

My backbone LAN is running on a 192.168.0.xxx subnet and my server is 192.168.0.20, and although i have the attached config i found on the web somewhere, it doesnt seem to work for me, i have tried changing the gateway addresses to that of my server but it doesnt work, what am i doing wrong?

; RB750
; Remove default configuration
; Winbox open new termial on left side of screen
; /system reset-config
; RB750 should reboot. Log back in using winbox. Ensure PC is plugged into Ethernet port 2
; Open terminal and it will ask to remove default config. Answer yes
; Assumption: Ethernet Port 1 will using a static public IP to backbone
; Ethernet port 2 -5 NAT
; Use DHCP pool range xxx.xxx.xxx.25 - xxx.xxx.xxx.200
; Maybe use static IP for Ubiquiti LAN and WLAN??? Not sure AP router or bridge
