title: Is there no way to use GCP TCP load balancing and IPv6 for a http/https website?
body: <p>I have a website all set up and ready to go in a Docker environment behind an NGINX proxy. I've configured SSL to the website works with http and https, and the website is working over IPv4.</p>
  
  <p>Now I need to add IPv6 support. It seems I can't attach an IPv6 address directly to my VM, I have to create a load balancer. I don't want to use the HTTP(S) load balancer, because that would involve re-doing my whole setup, configuring new certificates for the LB, routines for renewing them etc.</p>
  
  <p>So I've tried creating TCP load balancing, and it was fairly straight-forward for IPv4. However, when I try to create an IPv6 TCP load balancer, I'm forced to create a multi-region/global load balancer. When configuring a global load balancer, I have to select TCP port from a dropdown, and port 80 is not one of the options.</p>
  
  <p>Is it impossible to set up a website working with HTTP, HTTPS, IPv4 and IPv6 using TCP load balancing in GCP? Do I really have to configure a HTTP(S) load balancer?</p>
