Unable to get IPv6 to work (Apache)

WhiteDog
Hello, I am experimenting with cPanel 11.40.0.9 and IPv6. The server itself runs CentOS 5.9. When I test my domain using e.g. [url=http://ipv6-test.com/validate.php]IPv6 test - web site reachability I get the following result: Checking for AAAA DNS record = 2001:XXXX:4300:YYYY:3::1 Checking for IPv6 web server = web server is unreachable I can ping 2001:XXXX:4300:YYYY:3:0:0:0 using an external site Executing ping6 ipv6.google.com also works This is what i have done so far: 1. added "NETWORKING_IPV6=yes" to /etc/sysconfig/network 2. added "IPV6INIT=yes + IPV6ADDR=2001:XXXX:4300:YYYY:3:0:0:0 + IPV6_DEFAULTGW=2001:1af8:4300:YYYY:0:0:0:1" (+ = newline) to /etc/sysconfig/network-scripts/ifcfg-eth0 3. Added the range 2001:XXXX:4300:YYYY:3:0:0:0/112 in cPanel 4. Enabled IPv6 for a site using the cPanel interface. 5. Executed service network restart + /etc/init.d/ipaliases restart + apache restart Observation: When I enable or disable IPv6 using the cPanel interface for a domain, I receive the error "Request Timed Out". When I check back a minute later the domain is marked as "ENABLED". So it appears IPv6 is working on my server but that Apache is not configured to listen to it or blocking it. I also tried to temporarely disable the CSF firewall. Any idea what I'm missing or where the "Request Timed Out" comes from? Any log files I can check? Many thanks!

    Are the IPv6 addresses added to the Apache Configuration?

    Hi Kenneth, How do I check / change that? Is this not done when using the "Enable IPv6" or the "IPv6 Ranges" feature in cPanel?

    Look in /usr/local/apache/conf/httpd.conf. You should find, at minimum, an IPv6 address for each virtualhost associated with an account you granted IPv6 functionality too. This check is simply a standard troubleshooting step. If there are no IPv6 entries in the Apache config then something is amiss. In that case I recommend you open a support ticket with us

    Testing with [url=http://validador.ipv6.br]Validador IPv6 - Teste seu s"tio I get: * The server does not responds to a HEAD requisition. This is the most important test, this site is not accessible over IPv6! * It is possible to ping the server over IPv6. * The authoritative DNS server is accessible over IPv6.

    When I update in htpd.conf "Listen 0:0:0:0:80" to "Listen *:80" all the IPv6 tests start working :) I know the proper way to adjust this is via "Tweak Settings". Is it normal that I have to change this manually? Or should this change not be required?
