While two vps are seemingly identically configured, one refuses ftp connection with the error message
"port command failed" and "500 I won't open a connection to 192.168.1... (only to 'external IP')" and the
other works properly. What must be changed in CSF settings to make it work?
ftp not connecting (192.168.1...)
Re: ftp not connecting (192.168.1...)
solved
remote IP added under quick allow
(it was assumed to be there, but csf install happened from elsewhere and whitelisting in cpHulk did not do; odd anyway that this is necessary, but it has probably to do with passive ftp mode & NAT combo, while not having the port ranges for passive mode in either pure-ftpd.conf or csf.conf).
