h ipv4/ipv6 accesses on some servers I personally use.
===== SSH =====
add to /etc/ssh/sshd_config:
... r main lighttpd configuration file:
<code>
server.use-ipv6 = "enable"
$SERVER["socket"] == "0.0.0.0:80"... *,[::]
</code>
of course, ssl_listen have to be used only if you use SSL version of the protocols (that is, imaps or pop3s).
===== netfilter =====
