Hello. I'm having a little trouble getting ftp to work from behind a
firewall. I have gotten it to work through Netscape Communicator, ie.
I know the firewall computer's name, and the port to use, but I have no
idea how to make it work using the regular ftp utility. I would like to
get this working, because it is sort of a hassle downloading one file at
a time. Thanks for your responses.

If the firewall has an assigned port (say 8021) for ftp proxying, then
try:

<ftp firewall.box 8021
>220 Firewall Brand FTP Gateway ready
>Name (none):

>331 Guest login ok, send your complete e-mail address as password.
>Password:

This is how we do it with our firewall proxy agent. Different proxys
may be different. If you have a web proxy setup for http and ftp
access, then I don't think you can use the ftp service from normal ftp
clients, but I could be wrong.

You probably want to use passive mode (issue the PASV command). You must
look at your client to see if he can handle this.

Perfect! Thanks!

Now - any idea how to make this work with progs. like xdir, xftp, etc?

I just read something about this yesterday in the Red Hat 5.0
IP-Masquerading HOWTO. I'm not at home (where the machine is) so I can't
swear to this, but I seem to remember it saying that certain things don't
work through a Linux firewall, one of them being WS_Ftp to certain ftp
sites. They also made the comment that it usually works through Netscape.

Look through the HOWTO and see if you can find this.
