    Default CSF question (mostly) - Why open 3306 for outbound connections? PCI compliance issue.

    I notice that most have CSF configured for TCP_OUT = 3306 as we do. But now this has become a PCI compliance issue. So I am wondering about the logic in opening the MySQL port for outbound traffic? Is this something which is routinely used by the cPanel/WHM system?

    Not at all if you don't need it. I can't say for sure but I don't think CSF comes with this port open by default, either.
    This port is not open on any of my servers.

    CSF is a third party product produced by another company, which has a forum at this location:

    ConfigServer Scripts Forum

    It might be better to post on that location to ask this question to see if it is opened by default or not in any way.

    Thanks Tristan. I agree. They are in the UK and are not currently available. I needed a quick answer for this one.
