New Cisco 877 - FTP does not work as expected through port forward

We have recently replaced an old Sonicwall TZ170 with a Cisco 877
We have a port forward in place to allow FTP.  On the TZ170 it worked fine.  On the Cisco you can connect. but some functions do not work as expected.
Using the Windows XP FTP CLI client you can log in, but as soon as you do an ls or dir it will give the response the port command successful, and opening ascii mode, then stop:
EG:
FTP server.domain.local
Connected to server.domain.local
220-Microsoft FTP Service
220 Unautherised access is prohibited.  Session's are logged along with IP addresses
User (server.domain.local:(none)): test
Password:
230-Welcome to FTP
230 User test logged in.
ftp> ls
200 PORT command successful.
150 Opening ASCII mode data connection for file list.
------------------------
If ctrl-c is executed
------------------------
425 Can't open data connection.
ftp>
------------------------
Can issue other commands
------------------------
ftp> cd usa
250 CWD command successful.
ftp> pwd
257 "/usa" is current directory.
ftp>


LS or Dir do not work in other directories either
Everything works fine if you don't go through the cisco port forward and it all worked fine with the sonicwall
IOS is: c870-advsecurityk9-mz.124-4.T7.bin

I don't think it is related but we have another issue which has been posted here:  http://www.experts-exchange.com/Hardware/Networking_Hardware/Routers/Q_22986223.html
The config file has also been posted there

cisco routers need both port 20 and port 21 to be open and forwarded to the FTP host.

I have added port 20 to NAT rule and also to ACL
Still no more progress...
I'm guessing I will need to use Pasive mode now.  Is there a way to open multiple ports easily other than creating NAT rules which are 100 lines long and also ACL's which are equaly as long?

I have setup passive mode now in IIS to use ports between 5500 - 5520  and forwarded all of the NAT rules and also setup the ACL to include these ports
It works now if I use a dedicated FTP Client.  Flash FXP

However cannot get it working with the DOS FTP client or Internet explorer / windows explorer with either "use passive ftp" ticked or unticked.

Any idea's?   This client has always just used the windows FTP client to connect without any problems until this Cisco went in  : (

Actually, I'm more inclined to think that its an FTP server issue vs a router issue -
if you got past the login.

Sorry for not posting back quicker.  I haven't been onsite to test.  Below is the code minus passwords etc.
It currently works if you use a client capable of PASV mode.  But not the dos based client.
I have worked around and the client is happy to use WebDAV through internet explorer. This works fine.
