While I need the > OS to work dual-stack (which it does), I only need tomcat to work on tcp6. Tomcat committer here... There has been some fuzz on users@tomcat.a.o recently on IPv6. There seem also to be an issue with IPv6-mapped IPv4 addresses. I highly doubt that this is a Tomcat issue per sé, it is either an OS or JDK one. Greg knows better about the internals of the C implementation. A general advise is if it does not work with one connector for dual stack. Configure two with the specific addresses. Unfortunately, our entire enterprise network is IPv4 only, therefore I cannot test anything on our servers. Have you actually tried to bind a dual-stack socket with netcat/socat and see whether this works on FreeBSD? Please try and report. Michaelhelp
