forbidden (ipv6 vs ipv4) ?

[Webplace4u]

I recently set up a DirectAdmin server, and with several projects I’m running into the problem that some people get a “Forbidden” message when visiting the website, while others do not.


I personally suspect that it has something to do with IPv6 and IPv4, but I can’t seem to find the cause.


Does anyone have an idea where I should start looking for this issue?


Multiple users and multiple domain names.

Hello,

My wild guess they access a site via IPv6 which is not correctly linked to IPv4. But hardly would they see a "forbidden" error. So their must be something else. In anyway one should start with reading logs, as they might give some clues.
