The monitoring Log will tell you what Rule is being used for the FTP.
By default the FTP Application Filter does not allow uploads.

Hi,
I seem to have isolated a problem to the ISA server, but it doesn't
make sense to me.
I have several LAN to LAN IPSEC firewalls that endpoint at my ISA
server and connect to a LAN at another place I work and my home
network. I also have the ISA server setup to accept client VPN
connections using PPTP and L2TP.
These all work fine, but the other day, I set up an FTP server on our
internal network. I can FTP to it and put files on it form our
internal network, and all it's segments... so there are no internal
firewall problems.
The problem occurs when I try to "put" a file using FTP through any of
the VPNs. The VPNs are setup to all all protocols, there is no
filtering of any kind. I can connect to the FTP server and login I
can list, I can get files. I CAN'T put files. I can put files from
the internal network, all segments. But I CAN'T put files through the
VPNs. There is an FTP rule on the ISA server (2004 ISA) for our
public FTP server and that allows external users to FTP to the FTP
server in our DMZ. But the other system in our DMZ that I am trying
to FTP to, but going through a VPN has no rules set up for FTP or
anything else, and I would normally not think you need to right?
when I try to put, I get
ftp> put tmp.tmp
200 PORT command successful.
550 Access is denied.

Any insight on this problem would be greatly appreciated...
Thanks
