   Does anyone have experience in combining these two?   
      
   I run a he.net tunnel that arrives in my LAN on a dedicated Raspberry Pi that   
   acts as the end point of the tunnel. On the Pi I then run radvd across my LAN   
   to assign other devices an IPv6 address.   
      
   I have a Debian buster box that I have assigned a static IPv6 address in the   
   GUI config and from a terminal can ping -6 google.co.nz from the box just fine.   
      
   I can also run BinkD and poll out to an IPv6 address fine also.   
      
   The problem is getting incoming IPv6 connections to BinkD etc. to work.   
      
   I have UFW as the firewall, I have enabled IPv6 in the UFW config settings and   
   added ports like 24554 which when I check the status I can see the port is   
   enabled for both IPv4 and IPv6   
      
   To                         Action      From   
   --                         ------      ----   
   24554/tcp                  ALLOW       Anywhere                     
   24555/tcp                  ALLOW       Anywhere                     
   24554/tcp (v6)             ALLOW       Anywhere (v6)                
   24555/tcp (v6)             ALLOW       Anywhere (v6)                
      
   My router has port forwarding enabled from the WAN to the static IPv4 on the   
   Debian box and certainly for IPv4 traffic all is good.   
      
   I'm stuck as to know why I can't seem to get ports open for my IPv6 address   
   when I have UFW seemingly enabled.   
      
   Now the Pi that acts as the end point of the tunnel has a static IPv4 and IPv6   
   address perhaps I need to enable something in UFW for that address(ess)?   
      
   I'm also wondering if it's something to do with the tunnel stuff.   
      
   But it feels like I'm 90%+ sorted as I know the Debian box can happily poll   
   outbound BinkD traffic without issue.   
      
   Any help appreciated.   
      
   Best, Paul
