   I should add when I visit ipv6-test.com the webpage sees me as the following:   
      
   IPv6 connectivity   
   IPv6     Supported         
   Address  2001:4428:200:816c:3e:1994:f43d:f326       
   Type     Native IPv6       
   SLAAC    No      
   ICMP     Reachable         
   Hostname      None         
   ISP      Sixxs-nzwlg01 [New Zealand]    
      
   But that's not the address I think I should be using if I want the BBS to be   
   reachable for telnet, my hunch is I need   
      
   a) the Raspberry Pi firewall to forward? tcp 23 packets to that address in my   
   LAN   
      
   b) the world to see my BBS with the xxx::50 address (the new test AAAA one   
   that has a DNS record set up for it) and my Pi firewall to be configured to   
   send/rx packets to that address for port 23   
      
      
   Hmm... your's in moderate confusion... time to go for a walk methinks..   
      
      
   Best, Paul
