Need help with three Internet Connections in a school/office environment.

Hi all

I work in a school with a main office that has three Internet connections and a 100D. Two are dynamic IP Internet that are to be configured in WAN Link Load Balancing. The 3rd is a static connection for the main office staff.

The two Dynamic IP internet have gateways as follows and are configured as WAN Link Load Balancing.

10.0.1.253 (WAN1)

10.0.2.253 (WAN2)

Static Route shows below and Internet works in the classroom environment when policy is set for Class Network to WanLinkLoadBalace interface and NAT enabled.

wan-load-balance

My Static IP line is below and configured as 

201.128.148.254 (PORT1)

However when I configure a policy for the Office Network to Port 1 interface and NAT enabled. Nobody in the office can surf the Internet. When I connected my laptop to the router directly, I can surf the Internet.

Am I missing something? Do I need to add another static route or a policy route?

Thanks for any help.
