    Hi all,

    We have CSF installed on the cPanel server - Now we have a user who tries and connects via FTP and everytime they do, they can't make a successful connection and I've had a look at the logs and it shows the following:

    It shows them logging in and straight after they get the following:

    Apr 25 15:28:08 webhost kernel: Firewall: *TCP_IN Blocked* IN=ens160 OUT= MAC=00:50:56:04:8d:c1:c0:62:6b:e3:5c:80:08:00 SRC=60.228.XX.XX DST=5.135.174.2 LEN=52 TOS=0x00 PREC=0x00 TTL=112 ID=31089 DF PROTO=TCP SPT=53396 DPT=52838 WINDOW=65535 RES=0x00 SYN URGP=0

    Apr 25 15:48:08 webhost pure-ftpd: (flairr@domain.com@60.228.XXX.XXX) [INFO] Timeout

    Apart from allowing their IP on the "allowed list" which most likely will allow them connect - Is there any config changes we can do, so we don't have to keep putting people onto the allow list for them to make successful FTP connections.

    Cheers,
