IPv6 NAT-PT

[Nat-PT]

I am trying to get an IPv6 network communicate with an IPv4 problem but have been stuck on it for weeks to no avail. I wonder if anyone is kind enough to take a look at my running configs from both routers and see if they could lead me in the right direction. Im using Packet Tracer so my debug commands are limited due to IPv6 not been fully supported yet by Packet Tracer
