   Hello, Victor!   
      
   Thursday July 01 2021 20:31, you wrote to me:

   For example - rerouting traffic via VPN to get thru RKN's DPI.   
   Real life scenario :)

   Yeah, but you can have "host" part the same for several uplinks and change   
   prefix only on NPTv6 gateway.   
   It's the best ipv6 can offer for you, sorry.

   It adds more complexity and cannot be implemented easily in userland across   
   multiple OSes.
