What do I have to set up on the ISA server side to allow clients such as
WC-FTP32 and CuteFTP to work through it? What are the settings for the
client? Proxy OPEN? On the ISA side I have (well I think I have) enabled
FTP. Even set up a Proto Def that has a secondary of port 20. I have two
servers I am testing with. One is Integrated and one is Cache Mode. I know
(to an extent) that FTP works as far as the server is concerned because I
can FTP through IE 5.5 and 6.0.
FTP uses two well known ports (services): ports 20, and 21. One is
used for 'control', and the other is used for 'transfer' - if you can
get into an FTP site and issue commands to view directory listings,
etc, but are unable to download/upload, it's usually because the
'transfer' channel is blocked by a firewall.
Add a protocol rule that allows FTP, using the default ISA protocol
definitions for FTP. I wouldn't advise setting up an IP filter -
just use the built-in protocol definitions to allow FTP transfers.
