Balance One config to allow WAN1 & WAN2

Hi gurus,

I was using a Fortigate firewall which was sent for RMA (4weeks), and now i need to use the Peplink Balance One instead of the firewall to share my 2 WANs to my local network.

My current config :-

Dell core switch -
AD (DHCP server) -
WAN1 (100Mb) - static public IP
WAN2 (1Gb) - pppoe - username & password

Based on this, can one of the gurus please help me send a config file / config parameters for me to config the unit so our internet can be shared by the computers.

Any help from the gurus are much appreciated.
