   Hello, Victor!   
      
   Sunday July 04 2021 12:36, you wrote to me:

   With he.net you'll loose access to local google caches and to local CDNs.   
   With ipv4 I can forward only blocked subnetworks via VPN, with ipv6 and   
   without NAT66 I can't do that.   
      
    DP>> Yeah, but you can have "host" part the same for several uplinks

   Mobile IPV6 is an operator controlled tool to keep your IPv6 address intact.   
   But you are asking for exactly the opposite solution - to change your IPv6   
   address.   
      
    DP>> It adds more complexity and cannot be implemented easily in

    VS> OK, let's start anew with a simple setup. If there are two routers in

   Yes but you'll still have single routing table and timeout for client to   
   remove dead ipv6 address from interface and routing table is large enough to   
   be unacceptable for general use.   
      
   Best regards,
