I am configuring ipv6 for containers on proxmox.
All of the containers must be accessible from the surface, so, I assume, I must configure GUA (International Unicast Tackle) for every of the container.
Many of the containers are internet apps and for ipv4 I’ve a reverse proxy container (there’s just one exterior ipv4 tackle obtainable). All of the requests to ports 80/443 on host are NATed by iptables to that reverse proxy container after which to the vacation spot container.
I need ipv4 and ipv6 each working, does that imply that I ought to configure web-server on every of the container for ipv6 and nonetheless handle the reverse proxy container for ipv4?
If that’s the case, the digital hosts are principally can be doubled and the variety of web-servers installations can be growing with every new container, which does not appear to be an excellent answer to me.
I do know that utilizing ULAs with NAT66 is a foul factor to do, so the query is what are the very best practices for implementing such a scheme whereas holding each ipv4 and ipv6?
