>Description:
Compiling the lighttpd port using the WITH_IPV6 option (default) IPv6 support is compiled in but disabled in the default configuration. This alone could be considered as bug already, but there is another issue:

Enabling the IPv6 support in the configuration file /usr/local/etc/lighttpd.conf using the statement

server.use-ipv6 = "enable"

disables any IPv4 support in lighttpd. The server is unreachable via IPv4 when started using this configuration.
>How-To-Repeat:
Install lighttpd with Option WITH_IPV6 enabled:

Add this line to the configuration file:

server.use-ipv6 = "enable"

Start lighttpd and try to connect via IPv4.
>Fix:
According to <http://trac.lighttpd.net/trac/ticket/509>; this is a (Free)BSD-specific issue. Also it describes a workaround by adding this lines to /usr/local/etc/lighttpd.conf:

server.use-ipv6 = "enable"
$SERVER["socket"] == "0.0.0.0:80" {
# listen on all ipv4 interfaces.
}

I suggest to either add this workaround to the default configuration when lighttpd is to be installed with IPv6 support, or add a source patch to the port that makes lighttpd behave on FreeBSD as on other operating systems until the problem is fixed upstream.
