Currently, there is a known issue with varnishd on FreeBSD, where if you run it with "-a :80" it will only bind to IN6ADDR_ANY instead of both INADDR_ANY and IN6ADDR_ANY.
This is not easy to solve. The obvious fix, which is to bind to *all* addresses returned by getaddrinfo() instead of just the first one, will work on FreeBSD, but not on Linux, where you can't bind to the same port on both INADDR_ANY and IN6ADDR_ANY. On Linux, the current behaviour is good enough - binding to either INADDR_ANY or IN6ADDR_ANY will give you both. On FreeBSD, if we want both *and* the kernel has IPv6 support compiled in, we can bind to IN6ADDR_ANY and clear the IPV6_V6ONLY socket option (it defaults to on). If the kernel does *not* have IPv6 support compiled in, getaddrinfo() will still return both INADDR_ANY and IN6ADDR_ANY, but we binding to IN6ADDR_ANY will fail. I don't see any good way out of this mess - we're pretty much forced to special-case the "any" case. I've looked at other network servers, such as Apache and OpenSSH, and they pretty much universally solve (or rather avoid) this issue by explicitly specifying either 0.0.0.0 (INADDR_ANY) or :: (IN6ADDR_ANY) as the default listening address.
