Multiple ftp sites, 1 ip, diff ports

iis ftp:
FTP sites use two fixed local ports - the main port that any control
connections will come in on, and the port from which outgoing data
connections will be made. Note that outgoing data connections may be made
for outgoing _or_ incoming data transfers. The second port is one less than
the first port.

Your second FTP server is trying to bind to ports 22 and 21, but your first
FTP server already has ports 21 and 20 bound. Try 23 and 21.

Multiple ftp sites, 1 ip, diff ports Tom Allen

I have set up two ftp sites on SBS 2003 Std edition, default
has unlimited read-only access for my customers to download
unsecure company files, the second is restricted access for one
user only.

ftp 1, port 21
ftp 2, port 22

Cannot get port 22 to work no matter what I do and firewall
has been opened up for ports 20-22 on ftp.

If I test each ftp site seperately on port 21, it works perfect.

HELP!

I tried 23, didn't work, and I have ports 20 to 24 opened up
on firewall device too.

Any more help out there?

How do I know what port data is being transmitted back on?

Any way to log it?

It is X - 1
so if you got 21, then it uses 20
if you running on 23, then it need 22.

however, for inbound you only need 21 and 23.
20, and 22 are for outbound only.

when testing, use ftp.exe to test first.
