Hello,
It seems CSF blocks DHCPv6 ports by default, which can cause some confusion. I suggest that by default, CSF allows UDP6_IN for port 546.
DHCPv6 clients listen on UDP 546, and send responses to servers on UDP 547.

LF_SSH_EMAIL_ALERT: Ignore certain users
Two accounts need to regularly login to my server via SSH and sync, so I end up getting a ton of emails all day long. Can we add an option to ignore certain users when they login via SSH? (i.e., no email alert) As it stands now, I'm going to have to disable LF_SSH_EMAIL_ALERT entirely, which will we...

SASL Authentication Failure
Hey guys, It seems my server is getting a lot of failed SASL auth attempts via the maillog lately. This doesn't seem to be part of CSF's default configuration, so a lot of bad attempts got through! I added a custom rule for LFD to ban these "bad SASL" people, but I highly suggest you make ...

It appears the SELinux context in /usr/lib/systemd/system is correct, but the username still defaulted to my personal username, instead of root, for both lfd.service and csf.service Now inside the /usr/sbin directory, the ...

Incorrect SELinux Context (Fedora)
Hello all, I tried Fedora for the first time today, and CSF failed to install correctly (I've been successful with Centos for quite some time). Basically the systemd unit files, and the binaries get placed with incorrect SELinux context. I fixed the contexts in /usr/lib/systemd/system/ before I coul...
