   Some consumer routers mislabel IPb6 firewall opening as "port forwarding", mine   
   included.  Mine came with all inblund IPv6 traffic blocked by default (good!),   
   but to open a port to a specific host, I have to go into "IPv6 port forwarding"   
   (sic) and specify the port(s) that I want to open and the interface host ID   
   (last 64 bits of the IPv6 address) to allow traffic for.  Or I can specify that   
   host as an "exposed host", which of course, disables the firewall for that   
   specific IPv6 address.

   One would hope it does, and that there's a mechanism to open ports to specific   
   hosts in the firewal config.

   My router does speak of IPv6 port forwarding, but it's actually controlling the   
   firewall's packet filter.     
      
      
   ... Is fire supposed to shoot out of it like that!?
