HE IPv6 tunnel inbound

Hi, I have a Hurricane Electric v6 tunnel setup on an AWS (amazon web services) instance so that i can have ipv6 connectivity. I can ping and traceroute out of the tunnel fine, but am unable to access the tunnel from outside. For example, i am unable to traceroute to the tunnel address outside the tunnel address, even with the AWS instance firewall completely open. I would like to host a website accessible via IPv6, hence the tunnel setup. Is this possible? if so, what could i be doing wrong? Or is there a better was to go about this? Thanks, Grant
