I am trying to setup a server behind the DIR-615 with the latest firmware, but when I do an IPV6 port scan, it shows all ports as closed. I can ping IPV6 addresses such as ipv6.google.com no problem, and also view ipv6 websites, but the ports appear closed when scanning using tunnelbroker.net's ipv6 scanner. I am using their service to tunnel the traffic.
Does your router block incoming IPV6 traffic? If so, what are the recommended settings to prevent this? If not, any idea why this is happening?
