Dual ADSL WIC Issues

Hi,

I'm having some problems setting up a Cisco 1760 with dual ADSL WIC to two different ISP's

My end goal is to simply load balance the traffic over these two links.

At the moment I can only get traffic to flow over one of the links. I know the two links are fine as I have used a different router to double check they are working correctly.

ISP A works perfectly fine, it connects to the ADSL service and authenticates and then passes traffic. But ISP B connects to the ADSL service and authenticates fine but when I ping out to a host on the internet then the reply never makes it back. I have shutdown the dialer for ISP A while doing this.

Below is a copy of the config, any help would be much appricated.
