    I have a second router set up as an access point on my network. It is wired via ethernet to the main router. I have IPv6 setup on the main router using a Hurricane Electric tunnel. Some of my internal devices have link local IPv6 addresses.

    Question 1. Do I need to change some settings on the access point that would forward IPv6 requests to the main router? If so how?

    Question 2. How do you reach a device within your net work by using the IPv6 address? My main router now has an IPv6 address as well as some printers but when I substitute the link-local address for the IPv4 address in the web browser (to open the web interface for example) the device can not be found.

    Question 1. I would disable wan and DHCP on the access point, and check 'Use WAN port for LAN'. All the ports will essentially work as a switch so that there's no routing or NAT taking place. Then you could either use a lan port or wan port on the access point, really wouldn't make a difference. Best to let the access point act simply as a switch and for wifi access, and let the main router take care of DHCP, unless it conflicts with some other setup you have.

    Question 2. For web access atleast, make sure your surround the address with brackets [].
    ie. [2001:470:1f11:ff7::1]

    I have it set up as described (just wanted to make sure that I did not miss anything specific to IPv6) and I have no trouble reaching IPv6 addresses on the web, it is internal IPv6 addresses that I am unable to contact. At this point, I do not believe there is something wrong with my setup, I just do not know how to do it.

    Edit: Alright, with a little experimentation I have found out that you can reach the devices by putting the Stateless addresses or link-local address in the brackets for network devices. The router can be contacted by putting the Router IPv6 Address in brackets but the routers link-local address will not open the Tomato web interface.
