Packet tracer ICMP problem across Cloud-PT - simulating an ISP

OK so I'm trying to simulate the access part of an ISP. Its proving rather difficult though.  I can get all the clients to ping back to the interface on the ISP_EXG_R1 OK. I can dish out IP's to the customers WAN interface of their routers.

I can't for the love of me get the 'customers' public IP's to ping each other. Tracing a packet sees it being dropped on the routers interface where it should send the packet back out.

I have tried a 'ip route' but that did not work. I'm wondering if there is a limitation here. I can mapping multiple modems to one Ethernet cable...

Reducing noise on cisco equipment.

Running a home CCNA lab is NOISY to say the least! These aren't routers your generally going to be using under heavy loads for long periods, so if your like me and can't deal with the noise then the guide linked below maybe for you. It seems to cover all the basics such as the voltage and the pin layout although I would recommend testing with a multimeter and not the trial by error method used.
