It looks like it is a problem of setting up your router and NAT
service on the router, rather than a DNS issue.

>From the wolrd, mydomain.com, ftp.mydomain.com and www.mydomain.com
are seen as a signle IP/host (the public/WAN interface of your
router). That is the router that direct traffic to this or that.
