Port Forwarding - IPv6 address

[DarthChowder]

I can't seem to figure out how to get Astonishing Comic reader to find the server when I port forwarded. My Xfinity router/modem has assigned me an IPv6 address publically, which I think could be the reason. I have tested and the local network IP works just fine, but want to have access to this outside of my network. Any ideas?

Well you can use http://checkmyip.com or simular website to check what your ip4 is from the outside...
