Hardware ... DELL E510, 3GHz w/ 1 GB RAM
D-Link DI-524 router, Motorola SURFboard cable modem.
Software .. WinXP SR-3, "FTP Commander" and/or WS_FTP95

Somehow, I must have inadvertently changed the firewall settings on
my router as I cannot do FTP transfers when connected to the
SURFboard modem via the D-Link DI-524 router. I could swear that it
used to work.
I have no problem with general web surfing.
However, if I bypass the router, I can see the files on the server
and upload files. If the router is in the path, in cannot see the
contents of the directories or upload files.

Any suggestions? WindsurferLA

You are talking about an FTP client behind your router connecting to
an FTP server somewhere on the Internet right ?

In whatever FTP client you are using, check the Passive Mode (PASV)
setting for the connection. Tunr it off/or on and try it that way.

Checking Passive Mode did the trick.. Turning it on makes it work.
Thanks

Glad it worked out...I don't know why it would have changed. Most FTP
clients have a global setting, under the main options, which is applied
to all new connections. And then each individual connection detail has a
PASV mode override on a per-connection basis.

I never really did understand passive mode. My FTP site, inside my
network, requires that passive mode be turned off or it never gets a data
channel. The initial connection works OK, as you can see in the log, but
then it would say 'can't open data channel'. Everything I've seen says
PASV mode is for connecting to an FTP behind a NAT rtr...but not mine.
