Will that work for IPv4 <-> IPv6 (bidirectional)? What are my options for the highest performance, and preferably something that can run as a service? Set up IPv6 to IPv4 port forwarding with Socat on a virtual machine, ensuring dual-stack support for public projects using a simple script and Systemd. This can be accomplished by adding creating two DNS entries for my hostname: one for the IPv4 address and one for the IPv6 address. This is especially helpful for ISPs that use carrier-grade NAT, a very restricted but common option service providers offer. . For example to send all the DNS queries to an IPv6-only server (doesn't make a lot of sense, but that's just the basic idea): I have two servers, one is ROUTER - equiped with IPv6 IP and private IPv4 IP and the other one - WORKER has private IPv4 only. In rare cases, ping may work, but actual traffic does not flow. 7. Not ideal, since this masks the external IP addresses, and also creates some latency and additional CPU load when processing IPv6. It provides forking, logging and tracing, different modes for interprocess communication and many more options. Then, tried SOCAT IPv4 to IPv6 Routing on a dual-stack VPS I have in Los Angeles. My new main problem was that I can't assume to have that everywhere I roam, so most of the time I'll try to access from an IPv4-only entry point.
