   I see that you have added an IPv6 address to many-glacier.dyndns.org. I get no   
   connection.   
      
   But it is the wrong address anyway.   
      
   Windows has a "feature" called "privacy extensions". If this feature s enabled   
   it will use a temporary IPv6 addresses for making outgoing calls. The default   
   life time is 24 hours. After that a new temporary address will be used for   
   outgoing calls. One can accpet incoming on these tenporary addresses but it is   
   impractical because it keeps changing.   
      
   ipconfig will give you all the IPv6 addresses and some are marked "temporary".   
   Use the one not marked as temporary for incoming calls. The last one was:   
      
      
   2a02:a03f:4a2f:c300:4df3:890a:8ec1:7cc0   
      
   You may want to turn of this "feature". It is not much use when you run a   
   server and have to advertise the Ip address anyway.   
      
   netsh int ipv6 set privacy disabled   
      
      
   Cheers, Michiel
