Load Balancing over two links

Ok Let me explain it again... as GTM is the perimeter device so all the NAT's are transferred to the GTM device how it's configured is I have a wild card Virtual server 0.0.0.0/* performance layer4 it has a snat pool and the Irule. The Irule catches the traffic from a particular Private IP and uses the SNAT pool to map it to the particular public IP address using the configured SNAT pool.

 

Now if I have to make another wild card virtual server then I have two similar things and as per my understanding the more specific VS gets the preference over the more General VS. So wht my understanding says is that the existing irule that I have should only put the traffic of one of the proxy on one of the ISP and if that fails it should go to the next one.

 

I don't need to disturb the whole of the traffic going out from GTM to the ISP links I just need to handle the traffic for the proxy servers. That is the reason the next hop is not an answer for my query i think or I am not able to understand how I will make it work for proxies not the whole of the traffic.

 

This GTM is in redundant mode n the default gateway is a pool that contains the router IP.
