Reseller cannot use FTP-ideas?

[Svaha]

Hi all,
New to WHM. I have set up a reseller but she cannot access her client sites via ftp using either her IP or using client domain name (yes, it has propagated.)

But, she can access the client sites using the servers main IP to ftp.

No idea what is happening. Could it be the DNS zone setting? I have set up the reseller client ftp setting as:

FTP 14400 in CNAME domainname.com.

Is this correct or should I change this?

She can't access her client's account with her own domain's IP. She must use the main server IP (if the account is an IP-less account) or the IP assigned to her client.

If she can't access ftp.clientdomain.com, then she needs to check to make sure clientdomain.com has an A record to main server's ip. That FTP CNAME seems fine to me as long as domainname.com = clientdomain.com, not resellerdomain.com
