The WRT610N automatically sets up 6to4, but there is no mention of IPv6 in the interface. You can confirm this by checking your IPv6 address, if it start with 2002 you're using 6to4. Even if Comcast turn IPv6 on for you, it's unlikely you'll be using it with the original firmware.

DD-WRT doesn't support IPv6. At least not in any usable sense. To get it working, you need to create the RADVD configuration file, and write a script to calculate the 6to4 address and add it to the interface. There are no GUI options for configuring IPv6.

It has less functionality in this regard than the firmware that came with the router (a Linksys WRT610N). At least that automatically configured 6to4, even if it still didn't have any GUI options.

TCP isn't the problem. TCP relies on packets being dropped to know when to back off (it's the only way it can know the end-to-end bandwidth available). The network has masses of buffers now, nothing gets dropped in a timely fashion, so TCP keeps on sending.
