There is also a feature called Clear Control Channel that allows the

and password to be sent encrypted, then all other data exchanged over

the

control channel to be sent as clear text. In our case, this would allow

the

firewall to see the IP address and correctly "nat" it to the proper IP.

All

data sent over the data channel will remain encrypted. According to our 
vendor, this is a feature normally found only in third-party FTP

software,

and they are fairly certain this feature would not be available on the 
default AS/400 operating system FTP software."

From the IBM InfoCentre article on securing FTP with SSL

(http://publib.boulder.ibm.com/iseries/v5r2/ic2924/index.htm?info/rzain/rzain02.htm),
 
it seems that the FTP client can optionally encrypt only the data, while 
leaving the control information in cleartext, as suggested by the bank 
tech support people.

There are also some resources related to SSL+FTP at www.tylogix.com.  Mr. 
Dambrine did a talk on FTP from iSeries at the Toronto Users Group for 
Midrange System's annual education conference that was very informative.

Hope this helps,
Adam
