Next message: Arun K.: "Re: [LUNI] Multiple servers, 1 IP"
I though that there was a way to assign the name to the zone record? For
example:
ftp.mydomain.com. IN CNAME servername.
Will it determine the internal net IP address and foward data like this?

You can overload as many different names as you like on that single IP
address, but you can have only one machine with that address assigned to a
network interface. Splitting separate functions at one IP address off to
multiple servers isn't a big problem, but the tool you're looking for is
port forwarding. FTP, however, is a little messier than most services,
because it wants to open that pesky data connection on an unpredictable port
number...
You do have a firewall/NAT machine setup, right? If not, go grab the
IP-Masquerade-HOWTO and give it a once-over. Come to think of it, a
situation like yours might even be discussed in the current version.
BTW, you do know that the same FTP server (and logins accepted, and all
that) will answer to a connection from a client asking for any of the
aliases? HTTP can multiplex based on name, but FTP, like the majority of
internet services, assumes that the server-side is "named" by its IP
address, and has no way to know what FQDN was used in forming the original
connection request, if any.
