The struggle is real! We’re running dual-stack but had to whitelist certain subnets because some legacy gear just *freaks out* with ipv6 with ipv4 traffic.
Teredo tunneling worked okay for a bit, but performance was meh. Now we’re slowly replacing old hardware instead.
Side note: RFC 6555 (Happy Eyeballs) is a must-read for anyone dealing with this mess.
