Manual dual ISP Balance

Hi!

I have a multiple VLAN network and im trying to route internet traffic using address list between 2 ISP, both have /29 subnets i use 1 of the IPs of each ISP to NAT internet requests.

the idea is that i can control witch ISP a certain group of computers use to connect to the internet.

i´m using a CCR1036 for the task. i have 1 ether port as a VLAN trunk and 1 ether port for each ISP.
