h1. IPv6-Config
h2. Listening to "real" IPv6 addresses
Examples:
* @server.bind = "[::1]"@
* @$SERVER["socket"] == "[::1]:80" { ... }@
You are fine with these - they only listen to IPv6 in any case.
h2. Listening to not specified addresses
Examples:
* not setting server.bind at all, but using @server.use-ipv6 = "enable"@ in the global context
* @$SERVER["socket"] == ":80" { server.use-ipv6 = "enable" ... }@
These configs listen on the IPv6 "any" address; depending on your system this may also accept IPv4 connections (default under linux unless your distribution disabled it; check @sysctl net.ipv6.bindv6only@).
So such configs may break any time if the kernel default changes.
h2. Listening to [::]
If you use 1.4.27+ or have @sysctl net.ipv6.bindv6only@ = 1, this will listen on IPv6 only, otherwise on IPv6 and IPv4:
Examples:
* @server.bind = "[::]"@
* @$SERVER["socket"] == "[::]:80" { ... }@
h2. Recommended IPv6 setup
This works since 1.4.27 or @sysctl net.ipv6.bindv6only@ = 1
<pre>
# listen to ipv4
server.bind = "0.0.0.0"
server.port = "80"
# listen to ipv6
$SERVER["socket"] == "[::]:80" { }
# if you need ssl
$SERVER["socket"] == "0.0.0.0:443" "0.0.0.0:44" { <here your ssl options> }
$SERVER["socket"] == "[::]:443" { <here your ssl options again> }
</pre>
h2. Changes in 1.4.27
Since 1.4.27 lighttpd will set the "V6_ONLY" option for ipv6 sockets that were not empty hostname; i.e. these two will still use the system default for V6_ONLY as before:
* server.bind = ""; server.use-ipv6 = "enable"
* $SERVER["socket"] = ":443" { server.use-ipv6 = "enable" }
But for these cases lighttpd will only listen to IPv6 since 1.4.27 (or if @sysctl net.ipv6.bindv6only@ is 1):
* server.bind = "[::]"
* server.bind = "localhost"; server.use-ipv6 = "enable"
* $SERVER["socket"] = "[::]:443" { }
* $SERVER["socket"] = "localhost:443" { server.use-ipv6 = "enable" }
You can restore the old behaviour if you set @server.set-v6only = "disable"@ in the associated block. Use of this option is not recommended as long-term solution, as we will probably remove it again after some versions.
