Why?

What are you trying to do?

Your gateway doesn't have to be a public address (2001....)

You said that before, but I don't understand why?

IPv6 is 128bit.

The 64 just means you're using a /64 as opposed to a /63 or /65.

If you'd tell me what you're trying to accomplish, I can help you better.

The IP address in your initial post is for Comcast which supports dhcpv6-pd and the default path broadcast by radvd or dnsmasq should be the fe80 local link for br0. What version of dd-wrt are you running as current versions of dd-wrt for current routers support IPv6 (dhcpv6-pd, 6in4, static native) out of the box.

Note a few recent builds had a compile error which prevented radvd from starting but this has been corrected in the latest build.

FYI the post you referenced is a poor example as it's not really relevent in your situation

Also you may be better served asking how to setup dd-wrt with Comcast in the dd-wrt forums

Having a link-local address as the default gateway is not a problem. The most important thing is the router has a /64 static route pointing at the interface and the link-local address belongs to the router. I tried tp-link and also openwrt, the default gateway is a link-local address, the it is working correctly. I think you need to enter the public ip as default gateway if you want to save time for configuring a static ipv6, and easy to remember the gateway address.
