I have a Buffalo WBMR-G54 ADSL Router. The local IP address of the router is 192.168.1.1.
My Medion desktop computer connects connects to my Buffalo router using an Ethernet cable. I use the wireless...
> Zone Alarm free firewall and Avast antivirus have been installed on both computers
Your router is already acting as a "firewall" to block "unsolicited" traffic from reaching the computers on your LAN. So, unless you use Zone Alarm to block "outgoing" connections
(such as a computer-virus would try to make when "calling-home", there's little benefit
to using the Zone Alarm software.
> If I use Internet explorer to connect to http://myname.dyndns.org, Internet Explorer does connect successfully to the network. However, it invites me to enter the username and password for my Buffalo WBMR-G54 router - not for the storage drive.
While you are "forwarding" TCP port 21, you are not "forwarding" TCP port 80 (as used by the 'http://' protocol). So, when you connect from the Internet to your "public" IP-address, it is the router that responds, rather than one of your computers inside your LAN.
IMHO, it is "bad" that your router's web-interface is "exposed" to attacks from the Internet.
Either "forward" TCP port 80, or configure the router to use a _different_ port number for "remote management".
> If I enter the Router user name and password, that allows me to access the Router menus via the Internet, which confirms that my account at DynDns has translated the IP address successfully.
Correct. Hopefully, you're the only one who knows the correct username/password, and there is nobody that is doing "brute-force" attacks on your router, trying to login to "hijack" your router.
> if I use Internet Explorer or FileZilla to access ftp://myname.dyndns.org, I cannot connect to the router
Correct. The 'ftp://' protocol uses TCP port 21, which the router is "forwarding" to one of the computers on your LAN.

> Status: Connection established, waiting for welcome message
So far, so good.
Is FileZilla expecting a "specific" content in that "welcome" message, or will "any" response be "close-enough" ?
On a computer on the Internet, open a command-line prompt:
Enter FTP bob1944.dyndns.org
Do you get a "connecting" message?
Do you get a "connected" message?
Do you see the "welcome" message?
Note that the FTP protocol usually uses _two_ ports for File Transfer:
* port 21 for "control" (sending/receiving commands/responses)
* a "random" port for "data" transfers (including directory-listings)
It's this "random" port that your router is not forwarding.
However, some FTP-clients (probably including FileZilla) and some FTP-servers
support "passive" mode, where both the "control" and the "data" connections "share" port 21.
So, configure FileZilla to use "passive" mode, and _hope_ that your FTP-server supports "passive" mode.
