i have a problem. My client has got to links from two diff ISP's . one is 128 kbps and the other one is 512 Kbps. they r terminated at cisco 1721 router.now the whole lan traffic goes to Pix 515e, there they r nated to single Public Ip , then that traffic goes to the router.
Now the problem is that client wants the traffic to do load balancing ,so that he can use both the links . he also wants that he can switch from one link to another link without any config changes in case if one link goes down.
Please tell me the possible ways to do this as i think the problem is that the pix is doing nat to a single ip , so my router will see only a single ip so how can we implement load balancing or Pbr.
