IPv6 & DPC3941B

Any ideas on how to get the DPC3941B to not drop all ipv6 traffic coming from my lan?

 

Seems to me the DPC3941B is having trouble routing to my ipv6 addresses behind my Cisco ISR router.

 

My Cisco isr's wan can communicate to the DPC3941B, but anything from the LAN side of it get dropped by the DPC3941B's firewall on its was back in from the internet.

 

This has been a thorn in my side ever since we got comcast and I have litterally tried just about everything to no avail.

Here is a test I just did from a computer on the lan pinging a server offsite I was capturing the IPv6 traffic on

Lan - Offsite ServerLan - Offsite Server

This is an image of the firewall logs from the Comcast router, with the firewall showing current blocked attempts (I ran a few mroe ping tests after so timestamp doesn't fully lineup 1 min apart)

Thanks for reaching out to us today, Jermyrem. I'll want to take a look at the Comcast Modem to verify some settings so I can be sure I'm providing you with an accurate solution. Please, send me a private message with your full name and phone number to get started.
