PCC Load Balance 2x WAN with 4 Subnets

Hello All,

I would appreciate if someone can assist me in configuring my CCR1016. I currently have 2 gateways and need to load balance 3, soon to be more than that, subnets to use the load balance. I currently have it configured for 1 subnet using the guide: http://aacable.wordpress.com/2011/06/04/mikrotik-4-wan-load-balance-pcc-complete-script-by-zaib/#. Now I need to create 3 subnets and have them go thru the load balance.

Currently:

Eth1: 10.13.8.0/22
Eth11: Wan1
Eth12: Wan2

Need to:

Eth1: 10.10.20.0/29
Eth2: 10.10.30.0/29
Eth3: 10.10.40.0/29
Eth6: 10.10.4.0/29

Eth11: Wan1
Eth12: Wan2

Any advice is greatly appreciated. I am new to Mikrotik and I have issues understanding the programming.

Thanks,
