You can continue to use the old IPv4 subnet with a new server at Hetzner. With IPv6, it does not work unfortunately. Although I do not understand why I can keep all IPv4 (subnet and / or single), but not the IPv6 addresses. It’s annoying when you have to change […]

My patch for ISPConfig 3.0.5.1 also works for the latest version 3.0.5.2. Only the language file is not patched, but that can be easily realized by hand. Please understand that I do not find the time at the moment to adapt the patch accordingly – but that’s just a visual […]
I recently posted my solution for rewriting IP-addresses on mirrors here. Since yesterday ISPConfig 3.0.5 is available. The patch works with 3.5.0.1, too. Contrary to the old solution, there is now a patch available. You can now setup the IPv6-rewrite within the Interface. There is no IPv4 rewrite via the […]
As i described here, i change on a mirror the ipv6 according to the relevant subnet in the vhost-files. I added a rewrite for IPv4 and show you how to use this with the current RC. Use this only with ISPConfig-3.0.5-rc2 For ISPConfig-3.0.5-rc2 see my post here. In /usr/local/ispconfig/server/plugins-available/apache2_plugin.inc.php replace […]
There are various possibilities to deactivate IPv6 on linux-systems. You can modify entries under /proc, experiment with the kernel modules or god knows what all. I prefer to add just one entry to the grub-option. So i can easily reactivate IPv6 with one step. ipv6.disable=1 After a reboot, the IPv6 […]
