It's very basic...
client -> router/fw -tap-tunnel-> -hurricane-electric-> internet.
(the firewall/router is my normal ipv4 firewall but for ipv6 it acts as a router, thus the "router/fw" or "firewall/router".
but, router/fw -tap-tunnel-> -hurricane->electric-> internet. always works, and outgoing communications always works. This is only a problem for incoming communications.
